| Abstract |
This article conducts an analysis and research on the issue of crater growth when an eroding
rod penetrates a plastic target. By explaining the movement speed of the projectile deformation interface, the evolutionary mechanism of the projectile’s mushroom head under different impact velocities
is elucidated. Additionally, an analytical expression for the stress values in the high-pressure region of
the projectile head is provided. Based on the dynamic theory of spherical/cylindrical cavity expansion
and the power-law strain hardening material constitutive considering strain rate effects, an crater
growth model is established. The results indicate a better alignment between the cylindrical crater
growth model and numerical simulations. When determining the model’s boundary conditions, the
separation boundary conditions of the actual contact surface between the eroding rod and the
impacted target are summarized under ideal conditions. |
