Equivalence of J Integral and Stress Intensity Factor Approaches for Large Scale Bridging Problems

Abstract

The application of the J integral to problems involving large scale crack bridging is discussed. Using some simple examples for which close form analytical solutions exist, it is shown that there is a complete agreement between analysis based on stress intensity factors and the J integral. A simple method for deriving the bridging law from J integral measurements is outlined.
