摘要
应用半反推法推导出摩擦约束弹性广义变分二类变量的广义变分不等原理的能量泛函．由于半反推法不用拉氏乘子，可以避免由于拉氏乘子引起的临界变分现象．本文巧妙地处理了由于变分不等式引起的推导困难，为用半反推法导出更为复杂的接触问题的变分不等原理的泛函提供了一条新的思路．
The generalized variational functional of elastic contact problem is deduced by the semi-inverse method that can eliminate the variational crisis. The paper treats the complex problem caused by variational inequalities ingeniously and provides a new method for more complex contact mechanics.
