矩阵的积分 meaning in English
integration of a matrix
Examples
- Firstly , the paper introduces the principle of instituting contact interface element and the format of integral method for element stiffness matrix ; secondly , because of the zero of displacement and load of soil in the infinite boundary , the unique shape of element stiffness matrix is obtained for coupling the three different elements
文中首先阐述了接触元建立的方法以及单元刚度矩阵的积分方法；由于无限远处的土场位移、地震作用力皆为零，计算中对该单元刚度矩阵的形式不同于四节点等参元，文中推导了平行无限元的单元刚度拒阵方，并介绍了无限元单元刚度矩阵组装原理。
