Abstract
Ceramic/metal laminated composite armor systems have great importance and potential in defencetechnology due to their high ballistic performance and lightweight. In this study, it was aimed todetermine the ballistic performances, limits, and perforation types of light metals (with densities below5.0 g/cm3) used as ductile backing plates in laminated composite armor systems. In the numericalanalysis, SiC tiles of 5 and 10 mm thickness were used as the front layer. Al5083-H116, Mg AZ31B, andTi6Al4V light metal alloys in different thicknesses were used as the backing layer. While using theJohnson and Holmquist (JH-1) material model in SiC ceramic tiles, the Johnson-Cook (JC) materialmodel was applied for “.30 APM2” bullet components and metal layers. The analyzes were performedwith Ansys/Autodyn software. As a result of the simulations, among all the laminated armor systemsproviding full protection against “.30 APM2” ballistic threats with a collision speed of 878 m/s, the lowestareal density was determined as 54.245 kg/m2in 10 mm SiC/5 mm Ti6Al4V laminated composite armor.
