N2 - Based on the microscopic analysis experiments of residual projectiles after penetration experiment, the trace of the mass erosion of residual projectiles surface are investigated, and the physical mechanism of mass erosion is determined and summarized. Based on the results of microscopic experiment, the form of Archard model is modified to build a cutting velocity expressing cutting the head surface of projectile. Considering the effect of the heat produced by the friction in the penetration process on the cutting coefficient, the mechanism of friction is connected to the mechanism of cutting with the temperature, and the mass erosion model including the two mechanisms is built. In the model, the changing of the head shape of projectile is expressed by the method of node backspacing, then, the calculated results and the domestic and foreign typical experimental data are compared, and the results confirm that the model of mass erosion is valid.
