显示如何使用线弹性模型进行低循环疲劳（LCF）分析，尽管孔上的应力超过了屈服极限。孔的塑性基于小缺口的应力和应变场近似方法来处理。-This case shows how to use the linear elastic model to carry out low cycle fatigue (LCF) analysis, although the stress on the hole exceeds the yield limit. The plastic property of the hole is based on the method of small hole stress and strain field approximation.
