On the Fracture Stress for the Inclined Crack under Biaxial Load.

Abstract

The tensile vertical load required to fracture a biaxially loaded plane infinite sheet (in plane stress or plane strain) with an inclined crack is determined using the Griffith fracture criterion. The infinite plane geometry is used as a prototype enabling analytical demonstration of the qualitative features of the problem, such as the dependence of the critical load on the load biaxiality, crack orientation and Poisson's ratio of the material. Existing experimental data for a horizontal crack are summarized and found qualitatively in agreement with the results of the analysis.
