We study discontinuous Galerkin methods for solving elliptic variational inequalities of both
the first and second kinds. Analysis of numerous discontinuous Galerkin schemes for elliptic
boundary value problems is extended to the variational inequalities. We establish a priori
error estimates for the discontinuous Galerkin methods, which reach optimal order for linear
elements. Results from some numerical examples are reported.
