Interaction Effect of Arbitrarily Oriented Two Cracks in Isotropic Plate

Abstract

This report is aimed to obtain the general solution for interaction effect of arbitrarily oriented two cracks in isotropic material subjected to various loading. The cracks are present due to inclusions or irregularities in the material. The stress analysis is based on the theory of elasticity by using the Muskhelishvili's complex variable method. The complex stress function is determined for the plane stress condition to determine the stress intensity factor.

It starts with a general idea about the complex functions and its use in stress analysis for the less complex shape. The proposed method helps to study interaction effect of two arbitrarily oriented cracks.

Also the FEM solutions for stress intensity factor for the same case using ANSYS software are to be determined and result were compared for different loading condition as well as different crack orientation.
