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 variable—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 refs. [1], [3].
