Résumé
The phase-field approach is widely adopted for crack simulations due to its capability of naturally treating complex crack geometries such as merging and branching. Both the staggered approach based on the alternate minimization and the monolithic approach based on the limited-memory BFGS algorithm are developed for the phase-field crack simulations. Particularly, the limited-memory BFGS approach is introduced to overcome the convergence issues caused by the non-convex energy functional. This approach is further combined with a heat conduction problem to investigate the crack propagation under thermomechanically coupled conditions. Several numerical examples are provided to demonstrate the capabilities of the developed method, including crack simulations in the quenching problem and the thermal barrier coating problem. The performance of the developed method is also reported.
