| 摘 要： | 提出了一个分析横观向向同性土的各向异性非线性损伤力学模型，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，建立考虑非线性损伤引起的各向异性的弹性应力－应变关系，且应用此模型分析试验，结果与试验吻合。

| Abstract: | This paper presents a nonlinear anisotropic damage model. Based on thermodynamic theory, the concept of energy norm including anisotropic damage is made, and considering the concept of the damage potential, the evolution equation of damage is derived. Consolidated drained shearing test is chosen to illustrate the application of the model. Remarkably good agreement is seen between experimental data and numerical simulation. |
