Abstract：

It was summarized the definition, classification and application in metal forming of meshfree method. Meshfree method is classified according to approximation scheme and dispersal equation. Function approximation scheme is the foundation of meshfree method. Analyzing ability of meshfree method is influenced seriously by approximate accuracy, approximate efficiency and approximate feature. Although meshfree method is less mature than finite element method, it has more advantages than finite element method. For example, approximation function is independent of mesh, primary functions can include function series which reflect problem property and meshfree method with compact support function has banded sparse matrix. Messfree method is of wide application in metal forming fields because of its excellent solving ability for nonlinear problem.
