| 摘 要： | 采用有限元方法，并结合边界元方法，研究了高分子复合材料的力学问题，用可能接触区接触节点对方法，比例加载方法和库仑摩擦定律来模拟该问题。在受载过程中，随载的增加而逐渐改变接触边界条件。由于边界条件的不定性，导致了该问题的非线性，故了数学规划方法求解高度不定性的弹性接触方程组，进而求得接触区的接触位移和接触压力。

| Abstract: | The method of potential contact node pairs, the proportional loading and the Coulomb's law of friction are used to model the problems.In the loading process,the contact boundary conditions are changed with the increase of loading.Ilecause the non-linearity of the elastic contact problems may be caused by the indefiniteness of contact boundary conditions, the mathematical programming method is introduced into the solution of the highly indefinite contact equations.The contact pressures and contact displacements are obtained. In different contact conditions, many FEM numerical results are presented for polymeric composites. |
