摘要
基于虚功原理，推导了三维接触面单元的刚度矩阵，并引进预留单元的概念，避免了接触过程中由于接触面变化节点和单元需要重新编号的麻烦．
The stiffness matrix of three dimensional contact surface element is deduced basing on the principle of virtual work in this paper In order to evade rearranging nodes and elements due to variation of contact surface during contact procedure, the presetting elements are presented The method is validated by numerical examples
