Franz Roters: Crystal Plasticity Simulations: Fundamentals, Implementation, Applications

Crystal plasticity simulations aim to account for the crystalline nature of many structural materials in continuum scale simulations. The talk gives a short introduction into the physical mechanisms of plastic deformation. Next the implementation of crystal plasticity into continuum scale boundary value solvers is discussed. While in the past these have been mostly Finite Element solvers, in recent years spectral based solvers gained quite some attention. Benefits and shortcomings of the spectral solvers are highlighted. Finally application examples illustrate the whole spectrum of possible applications ranging from single crystal modelling all the way up to component scale simulations and the so-called numerical laboratory. As an outlook it is shown how additional fields, such as temperature, diffusion, and damage, can be integrated in the simulations. This new feature of the code is illustrated by some proof of concept examples.
