WebAbstract The response to normal impact of hard-steel blunt and conically-nosed projectiles on multi-layered plates of soft aluminum, both adjacent and spaced, as well as on adjacent disks of thin aluminum and polycarbonate, including sandwich arrangements, was studied experimentally in the subordnance velocity regime in the vicinity of the ballistic limit. WebThe response of multi-layered ceramic/steel targets to high velocity impact and penetration has been investigated through experiments and finite element simulations. Damage …

WebThen, impact experiments of a projectile obliquely penetrating thick steel targets at different striking velocities and inclination angles are carried out, and the influences of the striking velocity and angle of attack on the damage pattern, area and penetration depth are discussed to identify the ricochet phenomenon. WebDuring highly dynamic and ballistic loading processes, large inelastic deformation associated with high strain rates leads, for a broad class of heterogeneous materials, to degradation and failure by localized damage and fracture. However, as soon as material failure dominates a deformation process, the material increasingly displays strain …
