摘要
本文以增量理论为基础,将接触边界上的接触条件离散化,建立接触单元的概念,给出接触单元增量有限元方程,进而构成了平面变边界弹性接触问题的有限元方程。文中还给出了说明该方法的几个数值示例。
On the basis of the increment theryo, the concept of contact element is establised after the contact conditions are discretized. Meantime, the increment finite element equation of the contact element is obtained. Finally, the increment finite element equation of two-dimentional elastic contact problems with various boundaries is formulated. Several numerical examples are presented to demonstrate the method.
