The objective of this work consists of presenting a boundary element technique for analysis of bending plates where all algebraic representations of rotations for boundary nodes are avoided. The technique requires outside load points whose definition is extensively studied in this article.
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 g
