Resum
Crack propagation during the indentation test of a ferroelectric single crystal is simulated using a phase- eld model. This model is based on variational formulations of brittle crack propagation and domain evolution in ferroelectric materials. Due to the high compressive stresses near the indenter contact faces, a modi ed regularized formulation of the variational brittle fracture is coupled with the material model to prevent crack formation and interpenetration in the compressed regions. The s...
