“…For laminate armor, shear deformation promoted by the layering can have a substantial influence on the impact response [22], as can interaction between the layers [12]. The presence of a front-face polymer structure can even alter the failure mode of the underlying steel substrate [23,24]. Shear-plugging and spallation are the usual failure mechanisms for hard steel subjected to the impact by a blunt projectile.…”

• Polymer-aluminum laminates on the strike-face of steel plates enhance ballistic performance.• With judicious selection of substrate and laminate, a broad range of performance and weight combinations can be obtained.• There is both a reduction in magnitude of the substrate deformation and spatial dispersion of the impact.• The main function of the metallic layers is to stiffen the polymer without affecting the latter's viscoelasticity response. A study was carried out of pressure wave transmission and the ballistic penetration of steel substrates incorporating a front-face laminate, the latter consisting of alternating layers of thin metal and a soft polymer; the latter undergoes a viscoelastic phase transition on impact. The ballistic properties of laminate/steel structures are substantially better than conventional military armor. This enhanced performance has three origins: large energy absorption by the viscoelastic polymer, a significant strain-hardening of the material, and lateral spreading of the impact force. These mechanisms, active only at high strain rates, depend on the chemical structure of the polymer but not on the particular metal used in the laminate.

Penetration of flat-ended cylindrical projectiles into thin laminated composite plates was investigated analytically and experimentally. An analytical modeling was carried out for thin laminated composite plates by developing a new function for deflection by computing Von Karman nonlinear strains and by using the principle of energy balance. During the perforation process, different regions were considered for the plate, such as fracture region, elastic deformation region, delamination region, and undeformed region. The energy absorbed by each region was measured in small time intervals. To validate this model, the ballistic experiment is performed on the thin laminated composite plate near and beyond ballistic limit velocity. The samples were made from plain woven glass/epoxy using a hand lay-up method. In addition to the initial velocity, the residual velocity of the projectile was also measured using two parallel laser curtains. A comparison drawn between analytical and experimental results demonstrated a good consistency in the residual velocity of the projectile. Finally, the distribution of strains along the plate thickness direction over time, the different amounts of absorbed energy of the failure modes, delamination radius, and energy are assessed at near and beyond ballistic limit velocity.
