摘要
讨论了利用 Hellinger- Reissner二类变量广义变分原理解决定边界接触问题的混合有限元法 ,并且给出这种计算方法的数值实例。数值结果表明该方法在定边界弹性接触问题中的应用行之有效。
Constant boundary contact problems in practical engineering often occur. It is meaningful to precisely calculate stress and displacement in the contact area using an effective method. A mixed finite element method for the contact problems with constant boundary by Hellinger Reissner's general variation principle in two variates is studied and some numerical examples are presented. These numerical results show that this proposed method is effective.
