Resolving thermomechanical coupling in two and three dimensions

Thibault Duretz, Ludovic Räss, Yury Podladchikov and Stefan Schmalholz recently published a new study about multi-physics couplings with focus on thermomechanical interactions.

Thermomechanical strain localisation in 3-D for a cylindrical and spherical inclusion. The solution is obtained using a pseudo-transient GPU-based solver.

Their contribution (accessible here) assesses the ability of an iterative technique to resolve nonlinear interactions between thermal and mechanical processes. This new approach to solution is particularly well suited for parallel devices, such GPUs. The authors benchmark their proposed solver against a direct-iterative type of more classical approach (TM2Di).
