【Abstract】 In this paper, backgrounded on the Signorini contact problem, the equality between variational inequality and boundary value problems is studied. By use of Green formula, the foundamental solution and normal derivative of the solution, the boundary value problems in the two-dimensional domain into an equivalent boundary variational inequality is reduced, and the existence and uniqueness of solution of boundary variational inequality is proved.更多还原
