平面应变状态下广义Mises准则参数特性

Study on the Parameters of Generalized Mises Criterion at Plane-strain Condition

考察了平面应变状态下广义Mises准则参数表达式的基本特性。分析表明,平面应变状态下广义Mises准则会出现中主应力系数小于0的不合理情况,这可能就是导致预测与试验结果之间不一致的原因之一。

Numeric analysis on the characters of generalized Mises criterion at plane-stress condition has been done in this paper. It is found that the coefficient of intermediate principal stress is smaller than 0 at plane-stress condition, which maybe one of the possible reasons leading to the numeric analysis result inconsistent with the testing result when the generalized Mises criterion used.
