| 摘 要： | 以热力学理论为基础，提出考虑各向异性损伤的能量指标概念，构造损伤势函数，建立损伤的演化方程，进而建立软土的弹塑性各向异性损伤力学模型。应用此模型分析试验，结果与试验相吻合。

| Abstract: | This paper presents an elastoplastic anisotropic damage model. Based on thermodynamic theory, the concept of energy norm including anisotropic damage is made. Considering the concept of the damage potential, the evolution equation of damage is derived. Shearing tests are chosen to illustrate the application of the model, and remarkably good agreement between experimental data and numerical simulated ones is presented. |
