Abstract

We propose and analyze the finite volume element method for solving the Signorini problem. The stability and the optimal H1-convergence rate are given. Particularly, we establish a superclose interpolation estimate for the bilinear form of this method. Based on this estimate and the interpolation post-processing technique, we derive an O(h32)-order superconvergence in the H1-norm under a proper regularity condition. Finally, an asymptotically exact a posteriori error estimator also is given for the error ∥u−uh∥1∥u−uh∥1.
