โฆ Synopsis
This paper considers an asymmetrically kinked, semi-infinite crack in a two-dimensional solid under mixed-mode loading and a stress acting parallel to the main crack, the latter providing the non-singular stress term, T, in the Irwin-Williams expansion of the crack tip field. The aim of the study is twofold: First, to obtain an almost closed-form solution for the stress intensity factors at the tip of the kink with a view to explaining a curious result observed by many authors that under predominantly Mode I loading the first order solution in small kink angle is accurate for considerably large kink angles and, second, to study the effect of the in-plane tensile stress on the stability of crack growth. Where possible, the results are compared with those available in the literature.

A method is presented to analyze elastodynamic stress intensity factors at the tip of a branch which emanates at velocity v and under an angle r~r from the tip of a semi-infinite crack, when the faces of the semi-infinite crack are subjected to impulsive normal pressures.

Existing solutions to boundary value problems arising from an elastic sphere subjected to a body force have been primarily restricted to axisymmetric, conservative loading. In this paper, a method for solving the displacement equations governing the static equilibrium of an elastic sphere subjected
this paper the crack initiation under biaxial loading is studied. The crack extension angle and the critical stress of fracture are determined for various values of the crack inclination angle and for various values of the biaxial factor k. The Det.-criterion, developed by the author, was used. Acco
