In this work the possibilities and capabilities of high-resolution crystal plasticity
simulations are presented and discussed. Giving several examples it is shown how the
application of crystal plasticity simulations helps to understand the micro-mechanical
behaviour of crystalline materials. To avoid the high computational costs associated with
crystal plasticity simulations that arise from (i) the evaluation of the selected constitutive
law and (ii) the solution of the associated mechanical boundary value problem both
contributions to the runtime have to be kept small. This is done by (i) employing a rather
simple-and therefore fast-constitutive model and by (ii) using an effective spectral method
employing fast Fourier transforms for solving the partial differential equations describing the
mechanical behaviour. Here an improved spectral solver incorporated into the Düsseldorf
Advanced Material Simulation Kit (DAMASK) is used.
