Experimental study on anti-penetration mechanism of bolted composite protective structure with limited span under impact of low-velocity projectile

In order to study the influence of the bolt joint mode on low-velocity projectiles penetrating the composite protective structure, two bolt joint models which connect the composite target to the fixed frame were designed, the ballistic test of the bolted composite protective structure with limited span was carried out, and the bearing and failure characteristics of the bolted region, as well as the energy dissipation of each part of the...
