The prediction of fatigue lives of metallic components using the notch strain approach is based on local stresses and strains. These can be determined either by analytical approximation formulas such as Neuber's rule based on linear elastic stresses or by finite element analysis with elastic–plastic material behavior. The latter has the disadvantage of longer computation times.

使用人工神经网络估计弹塑性缺口应变和应力

使用缺口应变方法预测金属部件的疲劳寿命是基于局部应力和应变。这些可以通过解析近似公式（例如基于线性弹性应力的 Neuber 规则）或通过具有弹塑性材料行为的有限元分析来确定。后者的缺点是计算时间较长。
