Numerical Analysis of Impact Dynamics with Meshless Method

  • Dynamic impact processes was analyzed and simulated with reproducing-kernel particle method (RKPM).To solve the nonlinear problem, such as material nonlinearity and geometrical nonlinearity, incremental method was used.For a impact process with a normal impact velocity, the control equation for RKPM was deduced based on a small strain and incremental elasto-plastic constitutive law.The modified collocation method was applied to satisfy the essential boundary conditions.The simulation results of an impact process with RKPM show that the deformation velocity of a solid bullet obtained with RKPM is consistent with that calculated with ANSYS.
