Scope Recently observed rapid development of modern materials (e.g. advanced high strength steels for automotive industry, Ti and Ni based alloys for aerospace and nuclear applications, or multilayered, ultrafine-grained and nanostructured materials) is a stimulating factor for development of sophisticated numerical techniques supporting and extending experimental research. For example, the number of new metallic materials developed since the year 2000 has increased in an exponential manner. These modern materials are characterized by elevated properties which are the results of complex microstructures.
One of the numerical solution used to support development of these new materials is a multi scale modelling approach combined with conventional material models as well as models based on digital material representation. Digital representation allows to model microstructure with its specific features like crystallographic orientation, grain boundaries, phase boundaries, voids, inclusions, porous, composite threads etc. taken in an explicit manner. These methods are used to design specifically dedicated microstructures which meet very strict requirements.
The main goal of the symposium is focused on application of the multi scale concepts in structural mechanics to include physics based and heuristic modeling of material response, especially microstructure driven deformation and behavior mechanisms, material prognosis and state awareness, and materials impacts on novel, complex structures of metals, composites, ceramics etc.
