Characterizing and Modeling Penetration of Ceramic Armor.

Abstract

To assist in the design of ceramic armor, a micromechanical model of the penetration of a long tungsten alloy rod was developed. An understanding of ceramic comminution and fragment flow at the tip of the advancing penetrator was obtained by examining in detail the damage in ballistically tested ceramic targets and measuring the high-strain-rate behavior of ceramics in pressure-shear impact experiments and dynamic spherical cavity expansion experiments. A mathematical description of the results was constructed from the observations and measurements. The model was tested by implementing it into the DYNA code and performing computational simulations of ballistic tests.
