Abstract

Abstract: Numerical investigations were carried out on 1.27, 3.18, 6.35, 12.7and 19.05 mm thick 2024-O aluminum target against blunt nose steel projectiles of 12.7 mm diameter and 37.7 gram mass. Three-dimensional numerical simulations of the problem are carried out using finite element code ABAQUS. The ABAQUS/Explicit finite element code in conjunction with Johnson-Cook elasto-viscoplastic material model proposed by Leuser[1] was employed to perform the simulations. The present studyis concerned with the measurement of ballistic limit of deformable projectiles. The results obtained were compared with the experimental results conducted by [3, 4] and a close correlation between the two was found. The failure mode of the target was also found in good agreement. The results obtained showed a consistent increase in the ballistic resistance of target with an increase in the target thickness.
