Numerical modelling of behaviour of materials and structures under conditions of processing, manufacturing and exploitation is widely used in industry and research. The Finite Element Method (FEM) and alternative methods are commonly used to create a complex description of a particular deformation, thermomechanical or heat treatment processes. Applications of these methods are large, from modelling of simple processes to modelling the highly complex behaviour of entire structures (e.g. aeroplanes, buildings, implants). FE models are often combined with computational methods, such as Homogenization Method (HM), Monte Carlo (MC), Cellular Automata (CA), Molecular Dynamics (MD), etc to handle events that occur at the micro and nano scales. These models replicate phenomena, that take place in the material in different length and time scales. The potential for complex analysis of behaviour of materials and structures, including modelling of discontinuities and stochastic processes, is created. The objective of the minisymposium is to gather researchers working on various aspects of modelling of phenomena occurring in materials at various scales, from nano through micro and mezo to macro scale, and to enable exchange of experience.
The contributions in the following areas are invited:
- Conventional multi scale approaches based on the FE (XFEM, GFEM, FE2).
- Theoretical basis of various applications of multi-scale analysis techniques, such as Homogenization Method (HM), Monte Carlo (MC) method, Cellular Automata (CA) method, Molecular Dynamics (MD), etc.
- Alternative multi scale methods: e.g. combination of the CA-FE method, Neuro-Fuzzy Cellular Automata–Finite Element technique (nF-CAFE) or Neuro Expert Cellular Automata–Finite Element models (NESCAFE).
- Development of the statistically representative volume elements.
- Multi scale approaches based on the mesh free methods, particle-in-cell and other particle methods.
- Adaptive hp methods in multiscale modelling.
- Applications of the multi scale modelling to existing and future industrial problems such as melting, casting, welding, laser treatment, joining, forming, semi-solid metalworking, highly filled material processing, injection moulding, blow or compression moulding, vapour deposition, molecular beam epitaxy, and others.
- Solving microstructural problems, such as crack propagation, strain localization, microstructure evolution, solidification, phase transformation and others.
- Application of the mutli scale modeling to functionally grader materials, nano layers, sandwich materials etc.
- Development of new multi scale approaches.
- Optimization and identification in multiscale modelling.
