提出了一个分析横观各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(energy norm)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.
An anisotropic nonlinear damage mechanics model for analyzing transversely isotropic soils is proposed. Based on the theory of thermodynamics, the energy norm concept considering anisotropic damage is proposed, the damage potential function is constructed, the evolution equation of the damage is established, and the anisotropic elastic stress-strain relationship caused by nonlinear damage is established. This model was used to analyze the test and the results were in good agreement with the test.
