Abstract

Abstract

In this paper we consider uniform extension problems for joined two half-planes with different thickness and material behavior and one of which contains an elliptical hole, the other contains a crack. Along the boundary of these half-planes there is a stiffening stringer. Computational formulas are given in power series form by complex variahie-pertubation method. Results obtained here give extension to those of "Handbook of stress intensity factors". Numerical results of special cases in this paper coincide with those of references [1], [3].
