摘　　要：利用迭代法与不动点算法相结合给出了三维摩擦接触问题的一种混合迭代算法 ,克服了三维问题在接触面上因有无穷多个可能的滑动状态而无法确定带来的困难 .该法未引入任何人工变量 ,且简单易行 ,计算量小 。A mixed iterative method for 3-D frictional contact problems is proposed based on a combination of the iterative method and the fixed point method. This method overcomes the crux on the determination of the slipping angles at the contact nodes which is caused by the fact that the relative slipping may occur in any direction. This method is easy to be implemented without introducing any external variable. The numerical results suggest that this method is efficient and saves the computational amount.
