SPH using Constramed-Moving-Least-Square Method (C-MLS) is proposed and is applied to large deformation elastic perfectly plastic analysis. The spatial approximation of SPH is less accurate due to the only 0-th order consistency. Various Kernel approximations have been enhanced for the improvement of accuracy, In this study, C-MLS interpolation that improves MLS is applied to SPH. C-MLS is an improvement over MLS in the case when the approximation function does not pass through the node. The Poisson's equation for pressure is solved to take account of incompressibility in plastic analysis. Numerical analysis of longitudinal vibrating bar and cylinder impact are demonstrated to validate the present method.
