Abstract
A constitutive model for ceramics by Johnson and Holmquist has been incorporated and validated in the finite element computer program LS-DYNA2D. Using experimental data acquired at DREV, parameters for high density ceramics (around 98% theoretical maximum density) have been established. The effect of varying some of the parameters on the calculated depths of penetration into semi-infinite targets and the ballistic limits of armour has been investigated.
