- Abstract
- In this study, the peridynamic fatigue model for a homogeneous material is extended to the layered heterogeneous material. Thermal residual stress and the corresponding stress intensity factor are calculated, within the framework of the peridynamic theory, by considering the cooling process using a pairwise force function caused by the thermal loading effect. To avoid overlapping of the cracked surfaces due to compressive thermal residual stress, the notion of short range force (Macek and Silling, 2007) is newly introduced. In addition, an auxiliary reference configuration is used to define the cyclic bond strain in the constricted material. The proposed approach is validated by performing an illustrative case study.
