โœฆ Synopsis

A closed form solution for C* integral of two interacting cracks in plates under tension is developed on the basis of reference stress method. Comprehensive finite element (FE) creep analyses are carried out to provide the benchmark of the interaction evaluation of multiple cracks. Results indicate that more pronounced interaction is observed between the C* of double cracks and that of a single crack compared to that denoted by stress intensity factor (SIF). Overall good agreement is achieved between the proposed method for C* of multiple crack interaction and the FE results which provides confidence in practical application.

This paper includes the analysis of the interactions of two coplanar elliptical cracks, with equal or different crack sizes, embedded in finite thickness plates under uniform tension. The ratios of crack depth to crack length (bt/a~ and b,\_/a~.) are 0.25 and 1.0; the relative distances between two

Cyclic growth rate of a surface crack is complicated by the three dimensional stress field around the crack and also by an interaction expected between the growth rate at every position on the contour. An analysis, based on the total energy around a smfoce crack, derived a correlation between strain
