    Abstract
  • In allusion to the question of damage assessment for KE-Rod penetration on target, a single-impact damage index model was proposed based on numerical results of KE-Rod penetration on target with different rod-angles(varying from -60° to 90° by step of 30°) and velocity-angles (varying from 0° to 75° by step of 15°) using finite element method.Results show that the damage index increases with velocity-angle in general, but when the velocity-angel is 60° or 30°, the damage index reaches maximum while the rod-angel is the same.The result of simulation for vertical penetration is in good agreement with the experimental data, and the error is 4.06%, which validates the feasibility of the scheme.
