Instead, the crack tip opens smoothly and crack tip fields as well as the crack opening displacement are scaled by the J-integral. The paper concludes with a discussion on the range of load combinations which could be applied to two fracture test specimen geometries to obtain valid fracture toughness data. ().

N2 - The intent of this paper is to investigate mixed mode interface fracture toughness Jc. Full-field numerical solutions for a crack which lies along the interface of an elastic-plastic medium and a rigid substrate are presented. The solutions are obtained using a small strain version of the J 2-deformation theory with power-law strain the present article, results for loading causing only small scale yielding at the crack tip are described; in subsequent articles the.

Rivalta et al. considered the same situation as dealt with by Head () and derived a solution for the stress change by using a different method of analysis. Rivalta et al. went one more step forward and calculated the stress change induced by a finite-length, in-plane, interface-intersecting fault. However, all these authors considered. The problem of the growth of a crack located at the interface between two linearly elastic solids is considered when conditions promoting propagation along and/or away from the interface prevail. Both a stress and a maximum energy release rate criterion are examined.

Inverse square root, 1/√γ, singularity characterizes the stress field at the crack tip of homogeneous isotropic elastic media.

This 1/√γ singularity does not, however, hold for cracks present in inhomogeneous solids; such as, a crack terminating at a right angle to bimaterial interface, which is the subject of the current paper.
