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. |
