Abstract

A simple model is developed for the calculation of stress intensity factors for a lengthwise cracked beam subjected to transverse loading. The simple model is based on a GLOBAL/LOCAL approach that separates the GLOBAL structural behavior from the LOCAL crack tip zone dominated by singular stresses. The GLOBAL model is that of a frame while the LOCAL model is based on a novel application of the J integral. The accuracy of this approach is assessed by comparing it to a fully two dimensional analysis of an elastic layer containing a lengthwise crack.
