Interaction effect of rectangular hole and arbitrarily oriented elliptical hole or crack in infinite plate subjected to uniform tensile loading at infinity

Abstract

The problem of interaction of stresses due to the presence of a crack or elliptical hole near a rectangular opening in an infinite plate subjected to uniform stresses at infinity is studied in this paper. This problem is of importance in a passenger aircraft when a crack is found in the vicinity of the door. The stress concentration factors near the hole and the stress intensity factors near the crack tip are evaluated for various orientations of crack and various lengths and distances of the crack from the hole. In this analysis, the two complex stress functions are found out using Schwarz Alternating Method.
