Stress Intensity Factor of an Inclined Crack in an Orthotropic Plate under Compression

Abstract

A closed-form solution of complex potentials representing the elastic fields in an orthotropic circular disk of uniform thickness subjected to a self-equilibrium concentrated-counter-forces acting in the diameter direction is derived. Then the stress intensity factors at a tip of a straight crack located at the center of the orthotropic disk subjected to a counter-force compression was calculated using a derived solution and the body force method. The results of a present study are useful for evaluating a tensile strength of brittle materials such as anisotropic rocks.
