摘要
In this paper a simulation analysis of fatigue crack propagation was carried out in order to investigate the delaying effects of overload on fatigue crack propagation. The analysis was based on the Dugdale hypothesis, but the method of analysis used here is the extended body force method, which has been developed recently by the authors and is applicable to a wide range of problems. Based on the results analysed the retardation of crack propagation due to overloads was discussed quantitatively. The results of simulation analysis were compared with the experimental data obtained by other researchers.
