钢制压力容器残余应力的Mises屈服条件确定法

METHOD ON DETERMINING MiSES YIELD CONDITION OF RESIDUAL STRESS FOR STEEL PRESSURE VESSEL

利用Mises屈服条件建立了确定钢制压力容器焊接残余应力的方法,即只要测点进入屈服状态,就完全可以确定该点两个主应力方向的残余应力。并指出该方法是一种确定钢制压力容器残余应力的简易方法。

By the use of Mises yield condition, the method on determining the welding residual stress of steel pressure vessel was built. The residual stress of two main stress directions at measured point could be determined fully as long as the measured point came into yield situation. And pointed out that method was a simple method for deterring the residual stress of steel pressure vessel. It had the values for practice and popularization
