【摘要】：空间滑动面强度准则(SMP准则)根据实体空间的SMP平面上应力状态判断确定试样是否破坏。该准则在三轴压缩和三轴拉伸情况下退化为Mohr Coulomb强度准则。通过对实体单元的应力状态分析,讨论了SMP平面的空间位置以及SMP平面上应力状态,详细分析了SMP平面上应力状态点在三向应力莫尔圆中的图解方法。
[Abstract]:The spatial slip surface strength criterion (SMP criterion) is used to determine whether the specimen is damaged or not according to the stress state on the SMP plane of the solid space. The criterion degenerates to Mohr / Coulomb strength criterion under triaxial compression and triaxial tension. Through the analysis of the stress state of the solid element, the spatial position of the SMP plane and the stress state on the SMP plane are discussed, and the graphic method of the stress state point on the SMP plane in the triaxial stress moire circle is analyzed in detail.
