摘要
用边界单元法求解有摩擦弹性接触问题时,通过分析接触的基本形式,得出各种接触状态下的接触条件;将弹性体的边界积分方程离散,并与接触条件耦合得到接触问题的边界元离散线性代数方程组;采用迭代计算方法求出求解问题全部边界上的位移和接触压力的分布.
The elastic contact problem with friction is solved by using boundary element method.The contact conditions in various contact states are given and coupled with boundary integral equations for contact bodies.Then contact conditions and boundary integral equations are discretized as algebraic equations.Displacements and the distribution of contact forces within contact zones are found using incremental iterative technique.
