| Abstract: | In this paper, with the use of the friction problem in elasticity as the background, the existence and uniqueness for the solution of the nonlinear, indifferentiable mixed variational inequality are discussed. Its corresponding boundary variational inequality and the existence and uniqueness of solution are given. This provides the theoretical basis for using boundary element method to solve the mixed variational inequality. |
