Projectile perforation of multi-layered beams
WebA combined analytical and experimental study has been performed on the ballistic resistance of layered targets, in particular, of flat, relatively thin beam... WebFeb 10, 2024 · Multi-layered targets are assumed to be arranged in such a manner that the residual velocity of the first layer is treated as the impact velocity for the second layer and so on. Lastly, ballistic performance investigation on single layer with different thickness UHSC targets are carried out, see Table 7. 4 RESULTS AND DISCUSSION
