摘要
利用大变形有限元基本理论 ,以Goodman节理单元理论为基础 ,提出了大变形有限元节理单元模型 ,并推导了其相关的大变形有限元计算公式 。
Based on the basic theory of finite element method for large deformation and the theory of the Goodman joint element, a new joint element model of finite element method is proposed for large deformation. Then, the related formula of finite element method for large deformation is deduced. The problem of simulation of large deformation of discontinuous geological plane is successfully solved with finite element method. The present study is of theoretical significance and practical value to rock and soil engineering.
