| 中文摘要: |
| 按应力符号约定及主应力大小顺序，推导出了与之匹配的莫尔－库仑屈服准则主应力表达式、应力不变量表达式、塑性流动剪胀角参数表达式，揭示了莫尔－库仑屈服准则主应力表达式、应力不变量表达式、塑性流动剪胀角参数表达式与应力符号约定、主应力大小顺序间的相关联性，为合理选用莫尔－库仑屈服准则表达式及剪胀角参数表达式提供了适配性判据. |
| 英文摘要: |
| According to the stress symbol convention and the order of the main stress， the corresponding Moor-Coulomb yield criteria main stress expression，stress invariant expression，and plastic flow shear angle parameter expression are derived.The correlation between the principal stress expression，the stress invariant expression，the plastic flow shear angle parameter expression and the stress symbol convention and the order of the principal stress size are revealed.It provides the criterion for the reasonable selection of Moor-Coulomb yield criterion expression and shear angle parameter expression. |
