一个中心有切口的薄壁构件进行随机加载,尽管应力远远低于材料的屈服值,它仍然有可能会因为疲劳产生破坏。经过长时间加载后的破坏分析。使用 Rainflow 计数算法来定义了载荷情况,Palmgren-Miner 线性破坏模型计算破坏。-A center with a cut of the thin-walled member for random loading, although the stress is much lower than the yield value of the material, it is still possible because of fatigue damage. This case demonstrates the failure analysis after a long period of loading. Using the Rainflow count algorithm to define the load case, the Palmgren-Miner linear damage model is used to calculate the damage.
