DAMASK: the Düsseldorf Advanced Material Simulation Kit for studying multi-physics crystal plasticity phenomena

Franz Roters, Max-Planck-Institut für Eisenforschung, Düsseldorf, Germany

Here we present DAMASK as a unified multi-physics crystal plasticity simulation package. The solution of continuum mechanical boundary value problems requires a constitutive response that connects deformation and stress at each material point. This problem is solved in DAMASK on the basis of crystal plasticity using a variety of constitutive models and homogenization approaches. However, treating mechanics only is no longer sufficient to study nowadays advanced high strength materials. In these materials deformation comes along with phase transformation, significant sample heating, and damage evolution. Therefore, DAMASK has recently been extended to treat multi-physics problems. Following a modular approach additional field equations are solved in a fully coupled way using a staggered approach. We discuss the implementation and demonstrate the features of DAMASK on a number of case studies pertaining to the fields of TRIP, TWIP and dual phase steels.
