Evaluation of stress intensity factors under thermal effect employing domain integral method and ordinary state based peridynamic theory

In this article, several thermoelastic benchmark cases are studied within the framework of ordinary state based peridynamic theory (OSPD). By using OSPD, limitations geometrical discontinuity in fracture analysis can be overcome. Meanwhile, double nodes also avoided during crack definition. A domain integral method with thermal effect is applied calculating stress intensity factors (TSIFs). differential operators utilized to rewrite spatial derivatives integral. Numerical investigations TSIFs single and mixed-mode scenarios provided respectively, verified by reference solutions. Good agreements between OSPD solutions show high performance capability proposed analysis.
