OW1: Computational morphogenesis: understanding shapes emerging from mechanical interactions with environments

co-hosted by MEXT Grants-in-Aid for Transformative Research Area (A) “Material properties determine body shapes and their constructions Architect Bio)"

Biological cells and tissues form various shapes for proper functions in living organisms. Blebs and protrusions of the cell membrane, and folds of the intestinal wall are the typical examples. Complex shapes emerge from mechanical interactions of the cells and tissues with their environments. Understanding the underlying mechanism in morphogenesis is important not only for biology but also for engineering applications. The aim of this workshop is to bring together researchers who work on computational modeling and simulations of morphogenesis in nature and engineering. We will discuss recent advancements in mathematical models, and numerical methods for understanding all aspects of shapes.

OW2: Advances in structural and multidisciplinary optimization

Growing concerns in the recent years about effective design approaches for new or advanced materials/structures have triggered much interest in utilization of numerical technologies and development of structural and multidisciplinary optimization in various engineering fields.

OW3: Deep and machine learning methodology in the context of application to computational engineering

Application of artificial intelligence technology in the field of computational mechanics has been established for a long time. However, many examples of applying deep learning technology currently dominating the world to computational mechanics have not been shared and discussed very well yet. The objective of this mini-symposium is to discuss how to apply artificial intelligence technologies such as deep and machine learning to computational mechanics and engineering. We warmly welcome anything related to computational mechanics or artificial intelligence toward uniting both technologies into significant and beneficial applications. Particularly by using deep learning, it is necessary to discuss examples that make it possible to simulate objects that were difficult to simulate in the past, or to improve the accuracy of simulations that have been done in the past.

OW4: Frontiers of nonlinear, impact and instability analysis of solids and structures

Failures of solids and structures are often connected to their nonlinear behaviors and instabilities that can occur in various application fields. In many applications, harnessing the potential of such nonlinearity hinges on whether the deformation, fracture, instabilities and frictional contact of solids and structures can be understood, prevented, or controlled. Meanwhile, recently, researchers are planning to take advantage of the presence of nonlinear behaviors and instabilities in order to design solids and structures that have advantageous properties. To realize these concept, the additive manufacturing technique and multi-functional materials are also utilized.
Analyzing these phenomena requires the development of new modeling and computational approaches and techniques. The main purpose of this workshop is to bring together researchers and academics who work in the fields mentioned above, and to discuss the state-of-the-art theories and computational methods applied to nonlinear, impact and instability problems of solids and structures.

OW5: Mesh-based methods for hard-to-solve numerical problems in solid/fluid mechanics

This workshop aims to exchange opinions on solid/fluid topics that are difficult to solve with general-purpose software. With the spread of general-purpose FEM/FVM software, many numerical problems in solid/fluid areas can usually be solved without trouble. Meanwhile, there still remain some problems that are difficult to solve, e.g., severe large deformation problems, nearly incompressible problems, solid-structure coupling problems, and fluid-structure interaction problems. These problems frequently bring severe accuracy loss and lack of robustness due to various locking, pressure checkerboarding, numerical instabilities, and so on. In this workshop, recent progress in formulations of FEM, FVM, and various kinds of mesh-based methods to overcome these issues is discussed. Also, advanced utilization techniques of general-purpose software are discussed as well.

OW7: Multiscale simulation and materials modeling

Multiscale simulations and materials modeling are now becoming extremely powerful tools for exploring the physical picture of nonlinear mechanical behavior of materials in the entire range from micro- to macro-scale. Multiscale simulation can derive the macroscopic material behavior spatially and temporally incorporating the influence of underlying microscopic material structure. The information of the material behavior is used in the simulation in the larger length- and longer time-scale. Although these multiscale approaches have been developed for the decades and made a lot of successes in the application to practical and scientific problems, it is necessary to enhance exiting multiscale concepts, and to develop new multiscale methods for making further contributions to the structural analysis and material design.

The aim of the workshop is to bring together scientists and engineers working in the multiscale simulations and materials modeling, and to discuss the recent advances in the methodologies and applications of the multiscale simulations and materials modeling.

OW8: Advances in geotechnical engineering

In the field of geotechnical engineering, a growing demand exists to tackle with multiscale, multiphysics challenges that range from the microscopic particle-level behavior to the macroscopic ground response. These challenges encompass issues related to large deformations-flow dynamics, long-term prediction, and intricate spatial and temporal complexities. Despite significant efforts to model geomaterials and advance numerical simulation techniques, predicting and evaluating practical problems in this field remains challenging. The primary objective of this organized workshop is to fascilitate discussions and exploration of recent advancements and cutting-edge technologies in the field of geotechnical engineering, with a particular focus on computational mechanics. The scope of discussion encompasses a range of topics, including constitutive modeling, numerical methods, interaction between soil and structures, interaction between soil and fluids, geotechnical hazards, the quantification of uncertainties, and design strategies based on performance assessments.

OW9: Mesh-free and Mesh-less method

Mesh-free and Mesh-less method have been developed in the field of computational mechanics by taking advantage of their robustness against dynamic changes in free surfaces and propagation of discontinuities. While the advantages of these methods derive from their meshless nature, these features can conversely pose difficulties in the treatment of boundary conditions and in problems of multiphase flows with high density ratios. The purpose of this mini-symposium is to provide discussions for researchers of the mesh-free and mesh-less methods to share their recent knowledge and advanced insights. The topics are mathematical theory, discretization schemes, multi-resolution techniques, multi-physics analysis, boundary conditions, accuracy, adaptive analysis, parallel processing, large scale analysis, applications, verification and validation etc. for the mesh-free methods.
