| 摘 要： | 首次从泛函的极值的角度出发讨论了固体力学中库仑摩擦约束的线弹性广义变分不等式原理，给出了相应的最小位能广义变分原理，它为处理带库仑摩擦约束的固体力学的数值算法（如有限元法）提供了一个理论基础。

| Abstract: | It was discussed the general variational inequality in linear elasticity subjecting to Coulomb friction based on functional extremum and the responding general variational principle was proposed about the minimum potential energy;it gives a theoretical basis for numerical analysis in dealing with the problem in solid mechanics subjecting to Coulomb friction such as finite-element method. |

| Keywords: | frictional conditions the general variational inequality the general variational function |
