Abstract
The predictive simulation of materials with strong interaction between
microstructural evolution and mechanical deformation requires the
coupling of two or more multi-physics models. The coupling between
phase-field method and various mechanical models have drawn growing
interests. Here, we propose a coupled multi-phase-field and crystal
plasticity model that respects the anisotropic mechanical behavior
of crystalline materials. The difference of computational complexity
and solver requirements between these models presents a challenging
problem for coupling and parallelization. The proposed method enables
parallel computation of both models using different numerical solvers
with different time discretization. Finally two demonstrative examples
are given with an application to the austenite-ferrite transformation
in iron-based alloys.
