Abstract: In this paper, the reproducible kernel particle method (RKPM) is used for 2D nonlinear analysis with deformation Elastic-Plastic. Using the weak form of the problem, the discrete momentum equation and the approximate function of RKPM are substituted in the proposed method. Using the explicit method and Gaussian quadrature role and imposing the boundary conditions, the location and velocity equations of each particle are obtained. The penalty method is used for nonlinear contact algorithm. The discrete form of the Johnson-Cook's equation is used to describe the behavior of the material. Also, the Grunizen pressure equation is implemented for a given state equation. The computations associated with the experiments discussed in this paper were performed in the Fortran 90. To illustrate the validity of the method and the comparison of the efficiency with other researchers' numerical and experimental results, and a good agreement
