Abstract

The meshing method of spherical fragment penetrating target by LS-DYNA is introduced. With the material models of tungsten spherical fragment and LY-12 aluminum alloy target, simulation analysis of spherical fragments penetrating at different initial velocities and incident angles are made, from which the penetration charts, and the ricochet charts are obtained and discussed. The critical incident angles both for penetration and for ricochet are determined, and the terminal velocity and terminal angle of the penetrated fragments are analyzed as well.
