摘要:
In this paper, we study the superconvergence of the frictionless Signorini problem. When approximated by bilinear finite elements, by virtue of the information on the contact zone, we can derive a superconvergence rate of O(h(3/2)) under a proper regularity assumption. Finally, a numerical test is given to verify our result. (c) 2007 Elsevier B.V. All rights reserved.
