Abstract

In this paper, the effect of the variations of material combinations on the fracture behavior of an inclined crack terminated at a bimaterial interface was investigated. By using the complex-variable method, a comprehensive analysis of the state of stress and stress intensity factors (SIFs) was performed. Digital photoelastic technique was also employed to verify the theoretical results. Six specimens of different material combinations were prepared for a particular crack inclination angle. It was concluded that far-field effects usually found in the homogeneous case had to be included in the stress equations.
