โฆ Synopsis
The problem of a semi-infinite mode III crack terminating at a wedge-shaped inclusion consisting of bonded dissimilar materials is considered. The radial and angular dependence of the stress field upon material inhomogeneity is described in detail. Results for various geometries and elastic constants are illustrated numerically. The implications of these results with regard to the prediction of crack propagation are discussed.

A recent result of Stephenson[l] shows that, when finite deformations are taken into account, a crack under Mode II loading conditions in plane strain will open, at least near the crack-tip and at least for certain elastic materials. In this note, the matter is investigated further, and it is shown
Abstrat-By using the Hankel transform and the Fourier series, the stress intensity factor of a concentric penny-shaped crack in a finite long cylinder of a finite radius for mode III is determined. It is proved that the concentric penny-shaped cracks in an infinite long cylinder and in an infinite c
