The lecture presents a multi-physics, multi-mechanism, chemo-mechanical crystal plasticity and recrystallization modeling package together with several applications to engineering alloys subjected to thermomechanical and redox scenarios. The solution of such complex continuum mechanical boundary value problems requires constitutive laws that are based on material physics (considering effects such as microstructure, texture, chemistry, recrystallization, and damage) and that connect deformation, constitution, stress and damage at each material point. This task has been implemented in the free software package DAMASK on the basis of the crystal plasticity method using a variety of constitutive laws and homogenization approaches.

It is shown that a purely mechanics-based approach is no longer sufficient to study current advanced metallic materials. In these materials the elasto-plastic deformation via shear carriers such as dislocations, TRIP and TWIP effects is strongly coupled to recrystallization, phase transformation, dissipative sample heating, and damage evolution. Therefore, our theory has recently been extended to treat such chemo-mechanical multi-physics and multi-field phenomena, where we use also phase-field theories with both, conserved and non-conserved variables.

Dierk Raabe studied music (conservatorium Wuppertal, Germany), metallurgy and metal physics (RWTH Aachen, Germany). After his doctorate 1992 and habilitation 1997 at RWTH Aachen he received the Heisenberg fellowship award of the German Research Foundation and worked at Carnegie Mellon University (Pittsburgh) and at the National High Magnet Field Lab (Tallahassee). He joined Max Planck Society as a director in 1999. His interests are in computational materials science, phase transformation, alloy design, hydrogen, sustainable metallurgy and atom probe tomography. He received the Leibniz award (highest German Science award), 2 ERC Advanced Grants (highest European research Grant) and the Acta Materialia Gold Medal Award. He is a professor at RWTH Aachen and honorary professor at KU Leuven.
