Stresses Around Elliptical/Oval Shaped Hole In Finite Laminated Plate

Abstract

In this paper, a general solution for stresses around elliptical and oval shaped hole in finite laminated plate is presented. The plate is subjected to in-plane loading and stress functions are obtained using Muskhelishvili’s complex variable approach. The complex stress functions are represented in terms of Laurent series and constants of the series are derived using boundary collocation method. Effect of plate size, hole geometry, material properties, hole location and loading condition on stress concentration is presented. The results obtained through present method are compared with finite element solution and with the literature.
