Abstract

Because the impact duration of a projectile is very short (microsecond level), it is difficult to observe stress evolution of iron matrix under the impact in an industrial field and a laboratory. For the purpose of conducting an in-depth analysis on the residual stress on iron matrix surface after impact, a finite element model was established and simulated on a computer. The results show that: (1) the projectile rebounds after imposing an impact force, and the oxide layer in a certain area on the surface of hot rolled steel is broken and stripped; (2) when the impact velocity is small, along with the increase of which, the maximum Mises stress of iron matrix increases; when the impact velocity is high, along with the increase of which, the maximum Mises stress decreases slowly; when the impact velocity value is 35 m/s, the maximum Mises stress value is the biggest, which is 641.1 MPa; (3) under the impact force, a plastic tunnel is formed on the surface of hot rolled iron matrix, and the tunnel depth increases with the increase of impact velocity, forming a roughly linear relationship between them.
