Abstract
This paper presents an investigation on the failure of plates with double-edge notches and fatigue damage. The main aim is to develop a computational model for estimating the behaviour of a quarter-elliptical corner crack or a through-the-thickness crack located at semicircular edge notch. In such an analytical/numerical analysis, driving forces are evaluated by means of an analytical model and the finite element method, whereas the fatigue life is assessed employing a stress ratio-dependent crack growth law and the stress intensity factor.
