AlMsnct-A model for fatigue crack growth, similar to that of Majumdar and Morrow, is proposed where the ' crack growth rate is determined from the iow cycle fatigue and cyclic strcss~train response of tbc material. The model is for a constant stress range at infinity, but does allow for a v&able str

A simple method is described which allows the estimation of local stress intensity factors of two-dimensional cracks by use of the weight function basic relation. The method is applied especially to semi-elliptical surface cracks. Two examples are considered. The half-penny shaped crack under bendin
The fatigue and fracture performance of a cracked plate can be substantially improved by providing patches as reinforcements. The effectiveness of the patches is related to the reduction they cause in the stress intensity factor (SIF) of the crack. So, for reliable design, one needs an accurate eva
When these data are applied to the formula derived by M. A. Schroedl and C. W. Smith, the stress intensity factor K, can be calculated. Comparing this computed K, with that given by theoretical formula, we have found the error to be within t 5.20%. It is believed that the result of this test has met
