Abstract

In this paper, the thermal fracture behavior for a crack perpendicular to the interface in a functionally graded layered structure (FGLS) with a functionally graded interfacial layer is investigated. The plane strain state is considered. During the analytical procedure, integral transform methods are used to obtain the displacement and stress expressions. Then, by introducing an auxiliary function and using the residue theory and the singular integral equation method, the thermal stress intensity factor (TSIF) is calculated. Particularly, a crack intersecting the interface is considered. Some representative structure with different nonhomogeneity material properties and geometric parameters are analyzed and the corresponding TSIF is presented. The influences of the nonhomogeneity constants and the geometry parameters on the TSIFs are analyzed.
