The representation of failure criterions in generalized mohr space and its applications
失效准则在广义Mohr空间的表示及应用

The paper deals with the strength and the yield (failure) of materials in generalized Mohr space and finds out the transformations of failure criterions represented in the principal stress space and in the generalized Mohr space. A universal compatibility relations for the failure stress and the failure plane, which is independent of the failure criterions, is also discovered. For double shearing strength theory, owing to its representation in the generalized Mohr space, the theory is considered the equivalent of the maximal deviator stress.
