| 摘 要： | 详细讨论了广义塑性力学中屈服面和塑性势面的对应关系以及岩土材料的三类屈服面(即体积屈服面与 q 方向上及方向上的剪切屈服面)的基本特征, 尤其是提出了能考虑剪胀与剪缩的体积屈服面和应力 Lode 角θσ方向的剪切屈服面。指出在广义塑性力学中不必采用硬化定律, 就能得出塑性应变增量与应力增量的关系, 给出了求弹塑性矩阵的方法。

| Abstract: | The relation between the yield surface and the plastic potential surface based on the generalized plastic mechanics is discussed systematically, and the basic characters of the yield surface, especially of volumetric yield surface that can calculate dilatant volume strain and shear yield surface in stress Lode angel direction for the first time, are also discussed. The stress strain relation is obtained without hardening law, and the elastoplatic stiffness matrix is deduced with two methods. |
