Lifetime predictions for real loading situations—concepts and experimental results of fatigue crack growth
暂无分享,去创建一个
In this paper experimental results for real fatigue loading situations and loading changes are presented. It can be shown that the retardation effect depends on many factors, e.g. the overload ratio or the loading direction. Also, the lifetime is affected by the reconstruction of counting methods. In addition the results of simulations with the program code NASGRO are presented and verified by appropriate experiments.
