The Localized Method of Fundamental Solution for Two Dimensional Signorini Problems

In this work, the localized method of fundamental solution (LMFS) is extended to Signorini problem. Unlike traditional (MFS), LMFS approximates field quantity at each node by using quantities adjacent nodes. The idea similar domain type method. fictitious boundary nodes are proposed impose condition and governing equations formulate a sparse matrix. inequality problem solved indirectly introducing nonlinear complementarity function (NCP-function). Numerical examples carried out validate reliability effectiveness in solving problems.
