Hybrid phase-field modeling of thermo-elastic crack propagation
TLDR
In this paper, a hybrid phase-field method is used to simulate complex thermo-elastic crack propagation paths under the tempera-alignant conditions. But the model is limited to the case of a single phase field.Abstract:
Numerical modeling of the thermo-elastic fracture using a hybrid phase-field method is presented. The model’s capability to simulate complex thermo-elastic crack propagation paths under the tempera...read more
