dc.description.abstractThe study presents a comparative numericalinvestigation on ballistic performance of ceramic/metal armor structures. 2Daxisymmetric numerical model was developed for ballistic impact simulationsusing LS-DYNA® finite element software. The armor structuresincluded combinations of boron carbide (B4C), Al6061-T6 and 4340steel constituents. The interfaces in the armor structure were modelled with anepoxy resin adhesive. In order to define proper material behavior,Johnson-Holmquist-Ceramics material model for B4C andPlastic-Kinematic material model for Al6061-T6, 4340 steel and epoxy resin was used. The armor structures were subjected to7.62 mm ogive-nosed steel projectile impact. In the first section, theinfluence of back plate material on the ballistic performance of the armorstructure for bi-layers ceramic/metal configuration (ceramic front face andmetal back plate) was investigated for Al6061-T6 and 4340 steel materials undersame thickness and areal density. In the second section, the effect of removinghalf thickness of the metal constituent from the back plate and placing on thefront face was investigated for both Al6061-T6 and 4340 steel materials.Finally, the influence of adhesive thickness on the ballistic performance ofthe armor structure was investigated. Perforation response of the armorstructures were examined in terms of residual velocity of the projectile anddamage mechanisms of the armor structure.
