Thermal loading of a thin layer with circular debonding over a substrate

By using techniques appropriate to mixed boundary value problems, this stud y addresses the determination of stress intensity factors for a circular in terface debonding between a thin layer and a substrate subjected to nearly uniform temperature change. The solution method involves three-dimensional equilibrium equations of thermo-elasticity under axisymmetry conditions. Th e stress intensity factors are obtained by solving the resulting pair of co upled singular integral equations numerically.
