摘要
本文同时考虑了两个物体接触时表面边界非线性和材料非线性,利用内外层循环分开处理方法,解决了边界非线性和材料非线性的耦合,用增量迭代法求得收敛解。考题证明,该方法是有效而精确的。
In the present paper, both the surface boundary andmaterial nonlinearities arising from two contacting bodies aretaken into account. It can be shown that the influence betweenthe surface nonlinearity and material nonlinearity is aviodedwith inside and outside circulating methods. How to use theincrement-iterative method for the convergence olution. willbe demonstrated, and a test example is given to show the effectand accuracy of this procedure.
