Abstract
The aim of the study is to analyse perforation processes in explosively-cladded Ti6Al4V-AA1050-AA2519 plates impacted by fragment-simulating projectiles at velocity 500–750 m/s. A high strength titanium alloy is the striking face and a ductile aluminium alloy is the underlying, backing layer. The explosive welding may be an optimal technique of bonding of these two dissimilar metals without affecting their mechanical properties in a composite armour plate. The experimental observations of the plates deformation and failure are completed by a FEM simulation and a SEM fractography to analyse behaviour of such a layered metallic composite under impact loadings.
