Abstract

In this paper, the explicit finite element dynamic software LS-DYNA was utilized to investigate the process of projectile penetrating targets. The finite element model of projectile is simplified as two parts, warhead and balance part. In the finite element model, the threaded connection between warhead and balance part was set appropriately as contact. Projectile penetrated two or three target plates with different thicknesses, which are made of different materials. The results show that the contact between warhead and balance part fails in the penetration. After penetration, petal shaped crevasse appears on the target plate. While projectile penetrate the second or the last target plate, balance part may impact warhead after the failure of contact.
