失效准则在广义Mohr空间的表示及应用
The representation of failure criterions in generalized mohr space and its applications
-
摘要: 在广义的Mohr空间研究材料的破坏和屈服(失效)，找到了主应力空间和广义Mohr空间中失效曲面的变换，以及适用于所有失效准则的应力和失效面法向的普适相容关系. 对于双剪强度理论，根据它在广义Mohr空间的表示，将之归于最大偏应力理论一类.

Abstract: The paper deals with the strength and the yield (failure) ofmaterials in generalized Mohr space and finds out the transformations offailure criterions represented in the principal stress space and in thegeneralized Mohr space. A universal compatibility relations for the failurestress and the failure plane, which is independent of the failurecriterions, is also discovered. For double shearing strength theory, owingto its representation in the generalized Mohr space, the theory isconsidered the equivalent of the maximal deviator stress. -
