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.
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.
