摘要：
A meshless local Petrov-Galerkin method (MLPG) is presented for solving the clasto-plasticity problem in the paper. It is a truly meshless method using the moving least square (MLS) approximation as a trial function and the MLS weighted function as a test function in the weighted residual method. The incremental tangent stiffness method is applied in computation. Numerical examples show that the local Petrov-Galerkin method is applicable and effective for solving the elasto-plasticity problem.
