摘要
本文以损伤力学基础,将Valliapan三维各向异性损伤本构模型应用到有限元法计算中,建立了以应变损判据为基础的三维各向异性损伤演化方程。用改进的抹平式缝模式模拟混凝土童的损伤破坏,对拱坝进行了三维各向异性非线弹性有限元分析。
Based on damage mechanica,this paper has implemented Villiappan anisotropic elastic dam-age constitutive model in finite element analysis,built an anisotropic damage evolution law accordingto Mazars isotropic damage evolution law and applied smeared crack model to imitate concrete elementdamage failure. Based on these,this paper has made anisotropic nonlinear elastic analysis of an archdam with the aid of thc three-dimensional finite element method.
