| 摘 要： | 为了将应力空间中的强度模型转换为偏平面方程,反之亦然,可根据所选择的不同参考坐标轴来实现,有两种变换方法,且可以通过坐标变换实现互逆.通过这两种变换方法,可以相互证明偏平面极限迹线所具有的6折对称特征.而根据混凝土多轴强度模型的偏平面分析,表明混凝土的多轴破坏形态可以分为广义受拉和广义受压两种形式,这就暗示了统一的强度... |

| Abstract: | In order to convert the strength models in stress space into deviatoric plane equations according to the chosen reference coordinates,or vice versa,two kinds of transformation methods are presented,which can be carried out reciprocally by coordinate transformation.6-fold symmetry characteristic of the limit path line on the deviatoric plane can be proved by each other through the two kinds of transformation methods.On the other hand,multi-axis failure modes of concrete can be classified into generalized ten... |
