Stress Analysis of Infinite Orthotropic Plate with Two Holes

Abstract

Openings/cutouts are made into structures in order to satisfy some service re-quirements. These openings works as a stress raiser and may lead to the failure ofthe structure/machine component. In order to ensure safety and reliability, it is nec-essary to predict the behavior of stress pattern around openings/cutouts under theapplication of various types of loading conditions.A problem of laminated composite innite plate with a hole, under dierent typeof loading conditions is solved using Mushkhelishvili's complex variable method. Thestress analysis of innite orthotropic plate with two holes, subjected to dierent typesof loading, is solved using Schwarz alternating method. The generalized solutions ob-tained, are coded in MATLAB 7.0. The eect of centre distance, loading factor,material properties, and ber orientation angle on stress pattern is studied. Theloading conditions considered here includes uniaxial, biaxial, or shear loading at in-nity. The solution is veried with some of the existing solutions in the literatureand with nite element results (ANSYS). The results are in close conformation withthe present method.
