Stress Analysis of Infinite Isotropic Plate with a Internally Pressurized Square Hole Subjected to In-plane Loading at Infinity

Abstract

General solution for determining stress concentration around square hole in infinite isotropic plate subjected to in plane tension/shear at infinity and internal pressure and/or shear on hole boundry are obtained using complex variable method . For obtaining stress functions, Cauchy’s integral is evaluated for given boundary conditions. The generalize formulation is coded using MATLAB 6.5 and stress field around the elliptical opening is obtain. Some of the results are compared with finite element results using ANSYS.
