CTH analyses of steel rod penetration into aluminum and concrete targets with comparisons to experimental data

摘要

Calculational results are presented here for a class of intermediate-velocity penetration problems. The problems of interest involve penetration of moderate-strength target materials by high-strength projectiles. Two series of metal penetration experiments and a series of concrete slab perforation tests were simulated in this study. The computer code used for the calculations was the CTH code, which employs a recently-developed ''boundary layer'' algorithm for treating penetration problems such as these.
