Numerical investigation of penetration performance of segmented rods penetration into steel target

The penetration performance of blunt segmented rods was studied with numerical simulations by using hydro code ANASYS-AUTODYN systematically, and the dependence of penetration performance on the connect configuration, shape, spacing distance, impact velocity of segmented rods was also investigated. The numerical results indicated that penetration performance of the segmented rods is significantly greater than the parent continuous rods under some conditions. Simulations on the tests from open literature validate the present work, which can be used to guide the optimal design of weaponry segmented-rod projectiles.
