An adaptive thermo-mechanical peridynamic model for fracture analysis in ceramics

A thermo-mechanical peridynamic model using adaptive grid refinement is developed to investigate crack propagation in ceramics. Compared to a standard peridynamic model, using uniform grid, this approach allows to increase the resolution of analysis only in the critical zones. The performance of this approach in solving 2D thermo-elastic problems is examined and then it is applied to study the fracture of a ceramic disk under central thermal...
