A numerical study of ballistic behaviour of ceramic metallic bi-layer armor under impact load

M.K. Khan, M.A. Iqbal, V. Bratov, N.K. Gupta & N.F. Morozov
A 3D finite element model has been developed for studying the ballistic behaviour of bi-layer ceramic-metal target plates under the impact loads induced by the projectiles of different diameter to length ratios. The bi-layer target constituted of alumina 95, as front layer, backed by aluminium alloy 2024-T3 layer, has been impacted by steel 4340 blunt and ogival nosed projectiles of diameter to length ratios, 0.5 and 1.1. The constitutive behaviour of ceramic was modelled using...

BALLISTIC RESISTANCE OF CERAMIC METALLIC TARGET FOR VARYING LAYER THICKNESSES

M.K. Khan, M.A. Iqbal, V.A. Bratov, N.F. Morozov & N.K. Gupta
The ballistic behaviour of a bi-layer ceramic-metal target against steel projectile with varying layer thicknesses has been investigated using a three-dimensional finite element model. The bi-layer target was made of alumina 99.5 % ceramic front layer and aluminium 2024-T3 metallic back layer with an areal dimension of 100×100 mm and the thickness of both layers were varied, with the total thickness of the composite being kept as 10 mm and 20 mm. A steel 4340...
