Abstract:
Hydrocarbon resources still play a major role in the world’s energy mix. The quest towards cleaner and more efficient exploitation of hydrocarbon resources heavily relies on reducing the uncertainties in the characterization and evaluation of hydrocarbon reservoirs. Computational models and workflows play a key role to achieve this due to our limited knowledge of the rock properties, the multi-scale nature of porous media and our inability to conduct experiments at the reservoir scale. This mini-symposium aims to provide a platform for knowledge exchange in the field of reservoir evaluation using computational tools across multiple spatial scales. We welcome contributions in topics such as: advances in pore-scale simulation of fluid flow, computational modelling of rock deformation/geomechanics, computational upscaling techniques, machine-learning based workflows for formation evaluation and prediction of reservoir properties. We particularly welcome contributions that establish a close link between academic research and industry.

Abstract:

In recent years, the use of physics and biological-based innovative materials has recently influenced a diverse range of Engineering industries:Civil, Mechanical, Electrical, Medical, Aeronautics, Aerospaceand Mechatronics. These materials are carefully conceived to have a set of properties that cannot be found in nature. In the case of composite materials, new properties are raised by the right disposition and interaction of different materials, while the geometrical distribution and periodicity are the primaryconcern in metamaterials. For a further understanding ofthe behavior of these materials, it is necessary to carry out theoretical, numerical and experimental developments that allow their use in the design of new engineering products, which could not be suitably obtained with classic materials. In this sense, this Mini-Symposium aims to provide a forum for the dissemination and discussion of the latest advances in the physical-mechanical modeling of composite materials and metamaterials. Focus is on theoretical, numerical and experimental researches with emphasis on a synthesized and accurate description of the overall constitutive behavior of such complex materials and also to innovative computational methods. The topics of the Mini-Symposium include, but are not limited to: modeling and experimental testing of composite, periodic materials and metamaterials; Identification of equivalent homogeneous solids via advanced homogenization techniques; Local and nonlocal constitutive modeling; Mechanics of damage, plasticity, strain localization phenomena and material instabilities; Multi-field problems; Sonic wave propagation control; Energy transfers; Parametric and topological optimization; Mechanical and acoustical vibration control; engineering applications.

Abstract:
Faced with a future scenario of the scarcity of fossil fuels and large impacts on the environment, the use of renewable energy sources has become the wide object of studies that seek to diversify the global energy mix.
Among these various sources, there are other alternatives such as wind energy. The use of turbines for energy recovery is characterized as a low environmental impact conversion process, which can represent innovative solutions in the context of energy local, regional or national headquarters
Unexpected failures of wind turbine components, such as blades and towers are related to up to 40% of a wind farm cost. Reducing maintenance costs and extend wind turbines lifespan is a challenge.
The aim of this mini-symposium is to bring together researchers in computational mechanics, computer science, engineering and applied mathematics, and practitioners in wind energy systems, to tackle the problems of computer-based modelling & simulations.

Machine Learning for Biological Modelling and Simulation

Abstract:

Biological phenomena are among the most complicated systems to model. Biological systems

are genuinely multi-scale, multi-physics, and often hard to reduce to simple set of constitutive

and conservation laws. Such complexity translates in a high computational burden in simulating

realistic events, which in turn impedes robust parameter estimation and uncertainty

quantification. Fortunately, the advance of artificial intelligence has widened the spectrum of

techniques to cope with model complexity, providing new instruments in the toolbox of

scientists. Machine learning not only can help to drastically reduce the computational cost of

existing models; it can also unveil hidden correlations in high-dimensional data and

automatically translate them into effective low-dimensional models.

The purpose of this mini symposium is, therefore, to bring together experts in modeling and

machine learning for a fruitful discussion on how to blend diverse approaches for the common

objective of simulating complex biological systems and enabling their practical employment.

Oral contributions in the context of simulation-augmented machine learning, physics-informed

learning, neural network model reduction, multi-fidelity techniques, uncertainty quantification

applied to simulation of soft tissues, electrophysiology, growth mechanics and, more broadly,

biomechanics are welcome to be hosted in the mini symposium.

Nonlinear Response of Mechanical Systems Subjected to Contact Nonlinearities

Coordinators:

Papangelo Antonio – Department of Mechanics Mathematics and Management Politecnico di Bari, Italy  antonio.papangelo@poliba.it

Putignano Carmine – Department of Mechanics Mathematics and Management Politecnico di Bari, Italy  carmine.putignano@poliba.it

 

Abstract:

The dynamical response of mechanical systems is strongly affected by contact nonlinearities, which are often the prominent source of uncertainty when assembled systems are considered, due to the difficulties in assessing correctly damping and stiffness properties of contacts. Difficulties arise from the inherent multiscale nature of contacts, which always involves roughness over many length scales. Furthermore, very often soft materials are used for seals, dampers which exhibit time-dependent rheology and viscoelastic dissipation. The area of research is very active as it has implications in several areas of engineering such as dampers, tip-rubbing in turboengines, face-seals, joints, wipe-blade contact, finger-tip contact in humans. The symposium will welcome papers in the area of analytical modelling, numerical simulations and experimental characterization of nonlinear systems affected by contact nonlinearities. The symposium will cover, but will not be limited to, the following topics:

. characterization of the nonlinear dynamic response dynamical systems;

Abstract:
Established engineering works and projects show us that architecture and structure projects must be conceived and developed together. Despite this, what we normally see is a relation of distance between these two elements of civil construction. This mini-symposium aims to bring together the two fields of knowledge and show that the design of the structural system plays an essential role in determining the architectural design. Projects that explore the relationship between architecture and structure and the direct relationship between form and structure, where the definition of the structural system has effective participation since the design of the projects, provide works marked by structural boldness and major technological challenges. The mini symposium aims to gather contributions and obtain data that, through analyzes that use computational technologies and numerical methods, allow us to understand how the structural design allied to architectural creation provide innovative aesthetic results. Through these studies, it is possible to emphasize the importance of the technical knowledge for the realization of projects of good quality, evidencing the presence of the structural system in the architectural form. These analyzes contribute to the understanding of the importance of technical and technological knowledge for the production of an innovative architecture.

Abstract:
Epidemics of infectious diseases such as COVID-19 have been recurrent throughout history and can cause major damage in terms of both human lives and economic cost. The COVID-19 virus spread very quickly all over the world, in large part due to the high mobility characteristic of modern society. Although more than one year has passed since the beginning of the pandemic, we are still dealing with its devastating consequences. For this reason, mathematical models can be valuable tools, as they can provide estimates for possible scenarios of disease spread. This information may then help authorities make decisions about the allocation of limited resources in the event of an epidemic. This mini-symposium aims to provide a top-quality forum for the discussion among researchers from different fields, who are interested in modeling and controlling the spread of infectious diseases, with a particular interest in works applied to the context of the current COVID-19 pandemic. The MS topics cover (but are not limited to):
– Compartmental models in epidemiology;
– Epidemic models with spatio-temporal dependence;
– Agent-based epidemiological models;
– Computational fluid dynamics applied to investigate epidemics and related topics;
– Statistical methods in epidemiology;
– Graph-based techniques for analyzing the progress of an epidemic;
– Optimal control of epidemiological models;
– Uncertainty quantification in epidemiological models;
– Numerical investigation of protective equipment.

Phase-Field Modeling, Discretizations, and Applications

L. ESPATH – RWTH Aachen University espath@uq.rwth-aachen.de

Abstract:
Phase-field modeling dates back to the pioneering works of Van der Waals. Today, it is an important tool in engineering and natural sciences that involves the evolution of interfaces, ranging from the dynamics of multi-component and multi-phase fluids, binary alloys, polymer blends, boiling, fracture propagation, dendritic crystal growth, to the evolution of tumors in the macro-scale, to name a few. Phase-field models, also known as diffuse-interface models, have become an appealing alternative approach to interface-tracking methods. Such models implicitly track the position and the topology of the interfaces by applying smoothly varying scalar fields, implying in this way that interfaces are small regions of finite width where bulk interfacial forces compete with each other.
From a partial differential equation point of view, such models generally engender high-order
differential operators and possibly nonlinear equations. Phase-field models, thus, bring a new set of challenges for different scientific communities. In this mini-symposium, we invite contributions on high-order and isogeometric numerical methods as well as energy/entropy stable time integrators for phase-field models. We welcome numerical analysis and application to problems in fluid mechanics, solid mechanics, materials science, and life sciences or related research areas. We expect a multidisciplinary audience and a lively exchange atmosphere.

Plastic Instability and Fracture in Ductile Materials

Rodrigo Rossi – Federal University of Rio Grande do Sul  rrossi@ufrgs.br

 

Abstract:

Instability and fracture limit the performance, safety, reliability and manufacturability of a variety of engineering components and structures; for example, the crash worthiness of automobiles, the integrity of pipelines, the blast resistance of ships and airplane cargo holds, and the manufacturability of sheet metal components. The mechanisms of instability and fracture of these components and structures are influenced by multiple length-scales. For example, the structural dimensions set the constraint effects that influence phenomena such as plastic flow localization, and the microstructural length scales dictate phenomena such as void nucleation and growth. The phenomena that occur at microstructural length scales in turn inherits the effects related to the constraints imposed by the structural dimensions. The coupling or competition between these length scales may in turn result in evolution of new length scales. Correlating these length scales with instability and failure mechanisms will provide a direct link essential for development of new materials and structures as well as modeling and control of catastrophic failures. This minisymposium aims at gathering researchers from all horizons of computational mechanics in order to present their recent developments and results pertaining to modeling plastic instability and fracture in ductile materials.

Abstract:

The engineering community has widely acknowledged the importance of accounting for the effects of uncertainty on the performance of engineering systems. However, explicit quantification of the uncertainty is an extremely challenging task as usually, the behaviour of most engineering systems is characterized by means of highly refined numerical models whose is demanding. On top of that, the definition of appropriate models for describing uncertainty is far from trivial, particularly on those situations where there is lack of data, vagueness or imprecision. Hence, the development of methods for uncertainty quantification in computational mechanics has received much attention lately, with emphasis on its practical application for robust design.

The aim of this mini-symposium is addressing the very latest development on approaches for uncertainty quantification and robust design, including both probabilistic and non-traditional approaches. The scope of the mini-symposium is broad, as it covers: different models for representing uncertainty such as classical probabilities, intervals, fuzzy analysis, imprecise probabilities, evidence theory, etc.; novel approaches for uncertainty quantification applying meta-models (kriging, Gaussian processes, polynomial chaos, etc.), approximate or analytical solutions, advanced simulation methods, etc.; and practical applications of methods for uncertainty quantification such as robust design, reliability-based design, multi-objective optimization, life-cycle optimal design, sensitivity analysis, progressive collapse, etc. Both theoretical developments and applications involving systems of engineering interest are particularly welcomed in this session. This activity is organized under auspices of the Committee on Probability and Statistics in Physical Sciences (C(PS)^2) of the Bernoulli Society for Mathematical Statistics and Probability.

Recent Progress in Computational Methods for Particulate-based Systems

Coordinators:

Lou Kondic – New Jersey Institute of Technology  kondic@njit.edu

 

Abstract:

Dense systems build out of discrete elements, such as bacteria, colloids, grains of sand,

animal herds, or pedestrians are everywhere around us. During the last decade or so, a 

significant progress has been reached in connecting the properties of the basic building

blocks and their interactions to the macroscale properties of the systems considered.

Developing such connections requires better understanding of the mesoscale, large compared

to the scale of the elements, but small compared to the system size, and development of

novel computational methods. These methods emerge from a variety of disciplines: percolation,  theory of networks, computational topology, to name just a few main directions. The novel  computational methods that have been developed are more general than the systems to which they were applied, and may be of interest to the researchers in other disciplines as well.

I envision that the proposed minisymposium will allow for `spreading the word’ and making the researchers working on some of the systems listed above aware of the results and approaches developed for the other ones. Furthermore it is important to help the groups from South America connect to the researchers working on similar topics from the other parts of the

world.  The goal is to establish  new communication channels between the researchers,           

leading to further progress in this exciting field of research.

Abstract:
Machine Learning (ML) is fundamentally changing several industries and businesses in many ways and this is particularly true in the Oil and Gas (O&G) industry, as ML is an integral part of the ongoing digital transformation. For instance, ML is being applied to accelerate the discovery of oil reserves, improve subsurface characterization, optimize drilling operations, forecast oil production, minimize environmental impacts, thereby leveraging the daily work of geoscientists and engineers.
However, designing ML techniques in O&G requires addressing challenges not yet faced in traditional ML techniques applied to social and business domains. Therefore, a new area of research is emerging: Scientific ML, i.e., ML applied to scientific domains, such as geosciences, reservoir and petroleum engineering.
In O&G, obtaining ML models of physical phenomena requires the collaboration of scientists and engineers with in-depth knowledge of the geology of certain regions, in mathematical modeling and numerical methods, in various software and industry-specific data formats, in ML techniques, and in supporting computer science methods. Typically, they face problems at different levels, such as complex data preparation processes, mathematical modeling involving physical constraints, validation of hypotheses, data assimilation and uncertainty quantification and ultimately execution on large-scale computers in a scientific experiment lifecycle.
New research is needed to address these problems. This mini-symposium intends to gather researchers and professionals involved in the application and advancement of scientific ML in the O&G industry. There will be a wide range of presentations, ranging from fundamentals to advanced applications.

Theoretical approaches and practical applications are welcome. The organizers of this mini-symposium strive to provide a forum for researchers and practitioners to present and discuss current issues concerning UQ computational methods development.

 

 

Vibration Control

Coordinators:

Prof. Suzana Moreira Avila – Federal University of Brasilia avilas@unb.br
Prof. José Luis Vital de Brito – Federal University of Brasilia jlbrito@unb.br
Prof. Graciela N. Doz de Carvalho – Federal University of Brasilia graciela@unb.br

Abstract:
Dynamical systems are those whose state changes over time, an example is a pendulum oscillation. Such systems can be found in many science areas and its evolution law is described mathematically through differential equations. The control theory is an interdisciplinary theme originating in engineering and mathematics that aims to influence the behavior of dynamic systems. Mechanical vibrations are examples of dynamical systems. They are caused by time-varying excitations that are submitted components, set of components or complete structures. Excessive vibrations in these systems are not desirable as it may compromise the performance and also cause its collapse. In this context, the vibration control is a technology which aims to reduce excessive vibration levels through the installation of external devices or the action of external forces which promote changes in the stiffness and damping system. The main objective of this mini-symposium is to bring together experts working in vibration control and its application to present and discuss the latest developments in the field.
