A 3D elastic-plastic finite-element analysis is conducted to study crack-growth behavior of thin and thick center-cracked specimens under constant-amplitude loading conditions. The numerical analysis and the specimen configuration and loading are des

A strip crack closure model, based on the Dugdale-Barenblatt model but modified to leave plastically deformed material in the wake of the crack tip, was investigated for various aspects of fatigue crack growth behaviour. A constraint factor was intro

A boundary element method (BEM) was specially developed for a crack under crack face pressure in arbitrary two-dimensional problems. It is based on the basic stress solutions for an infinite plane with a crack loaded by body forces and moment at arbi

An analytical method for the analysis of fatigue crack growth in residual stress fields is provided in this study based on an elastic-plastic crack closure concept. Crack opening stresses are calculated by a method which is mainly based on the Dugdal
