FOR 797: Analysis and computation of microstructure in finite plasticity

Type of Funding: DFG Programmes, Research Units

We intend to address the need for a fundamental understanding of the physical origin, the mathematical behavior, and the numerical treatment of models which include microstructure. We shall pursue this aim by a joint effort involving mathematical analysis, numerical analysis, computational mechanics, material modelling and experiment. The mathematical analysis will be based on methods from the calculus of variations, while in the numerical implementation global optimization algorithms will play a central role. The modeling will cover all length scales, from the atomic structure up to macroscopic samples. The development of the models will be guided by experiments on single and polycrystals, and results will be checked against experimental data.
