补充资料：应变集中
受力零件或构件在形状尺寸突然改变处出现应变显著增大的现象。应变集中处就是应力集中处。某横截面上的局部最大应变与该截面名义应变之比，称为应变集中系数。名义应变由名义应力和材料的应力应变关系算得。当应力和应变都在弹性范围内时，应变集中系数与应力集中系数是相等的。在弹性范围内，用弹性理论或光弹性方法确定的应力集中系数，称为弹性应力集中系数，或称理论应力集中系数用Kt表示。进入塑性范围时，因有屈服阶段，应力集中现象有所缓和，塑性应力集中系数将比弹性时的Kt值小些；而塑性应变集中系数则比弹性时的Kt值大些。按照诺依伯公式，。弹性范围的应力集中系数Kt完全决定于构件的形状尺寸，而与材料的应力应变关系无关。如果已知材料的应力应变曲线、名义应力和名义应变以及理论应力集中系数Kt，则可按如下方式求得塑性应力和应变集中系数:先求得＝常数式右边的常数值。此式在以应力为纵坐标而应变为横坐标的图上代表一条双曲线（见图），该双曲线与材料的应力应变曲线的交点的坐标为、，于是算出 ，。诺伊贝尔公式也适用于线弹性材料情形，即应力应变关系为胡克定律的情形，这时。
