Coupling of Reproduce Kernel Particle Method and finite element method for impact dynamics simulationکنفرانس ملی مهندسی مکانیک ایران
In this paper, the reproduce kernel particle method (RKPM) is employed for 2D nonlinear analysis with deformation Elastic–Plastic. Using weak form of the problem, the discrete momentum equation and approximate function RKPM are substituted in the proposed method. Using explicit method and Gauss 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 Johnson–Cook’s equation is utilized to describe the behavior of the material. Also, the Grunizen pressure equation is implemented for the given state equation. The computations associated with the experiments discussed in the present paper were performed in Fortran 90. To illustrate the validity and efficiency of the method comparisons are made with numerical and experimental results of other investigators and a good agreement is obtained<\div>
