摘要：Meshless methods are became an alternative to most popular numerical methods used to solve engineering problems such as Finite Difference and Finite Element Methods.Because of element free nature,problems are solved using meshless methods depending on the general geometry and conditions of the problem.Mixed Meshless Local Petrov-Galerkin (MLPG) approach is based on writing the local weak forms of PDEs.Moving least squares (MLS) is used as the interpolation schemes.In this study contact analysis problem is modelled using Meshless Finite Volume Method (MFVM) with MLS interpolation and solved for beam contact problem.Meshless discretization and linear complementary equation of the 2-D frictionless contact problems are described first.Then the problem is converted to a linear complementary problem (LCP) and solved using Lemke’s algorithm.An elastic cantilever beam contact to a rigid foundation is considered as an example problem.
