Abstract | Fatigue life is the summation of crack initiation life and propogation life, but the technique to evaluate initiation and propogation of the crack by a unified theorem has not been established yet. Toyosada et al. proposed a fatigue crack propogation law based on re-tensile plastic zone's generated load (RPG load). Moreover, they established a simulation code for analyzing fatigue crack propogation behavior in various aluminium alloys. An investigation is necessary to check the crack opening behavior in case of both experiment and simulation for each aluminium alloy, before conducting estimation of fatigue crack propogation behaviour in aluminium alloys. In this study, the crack opening profiles in aluminium alloy 5083 were estimated by Dugdale Model and these profiles were compared with those by experiments and FEM subject to CCT specimen and a coefficient, called plastic constraint factor was introduced, which should be applied to Dugdale Model to achieve improved crack opening profile in aluminium alloy |
