|Title:||Fatigue endurance design of plates with two semicircular edge notches and one quarter-elliptical corner crack or through-the-thickness crack||Journal:||International Journal of Fatigue||Volume:||127||First page:||45||Last page:||52||Issue Date:||1-Oct-2019||Rank:||M21||ISSN:||0142-1123||DOI:||10.1016/j.ijfatigue.2019.05.021||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.
