三维多体摩擦接触问题边界元法及应用

Research on 3-D Multi-body Contact Problem with Friction by BEM and Its Application

从边界积分方程出发，推导了5个物体摩擦接触的边界积分方程，在求解接触问题的迭代过程中，应用了“凝聚法”．对一个由不同材质组成的接触问题进行了计算分析，取得了良好的分析结果．

Based on the fundamental boundary integral equation, the boundary integral equa-tion of five-body contact with friction is derived. During the iterative process of solving con-tact problem, the method of condensation is applied. Contact problem composed of differ-ent materials is analysed and the better result is gotten.
