Combined with the experience of AUTODYN three-dimensional nonlinear finite element analysis software, the effect of external Gap and Trajectory two Lagrange / Lagrange contact algorithms on simulation calculation efficiency and reliability of piercing is studied through an example. Through the comparison between the simulation results and the experimental results, the combination of solvers and contact algorithms suitable for simulation of armor piercing process is given.
