Experimental Study on Failure Mechanisms of Novel Visco-Hyperelastic Material Target Under Ballistic Impact Conditions

The main aim of the study was to define the static and dynamic properties of novel visco-hyperelastic material and its behavior under 7.62 × 25 mm Full Metal Jacket (FMJ) projectile impact condition. Mechanical tests were performed in both quasi-static and dynamic conditions. Uniaxial quasi-static compression tests were performed at different temperatures in order to characterize the influence of thermal effects on the plastic flow of the material. The Split Hopkinson Pressure Bar (SPHB) apparatus was used to assess strain rate sensitivity of the novel material. Residual velocity of projectiles (after perforation of the target) was recorded during the test allowing to evaluate energy absorption and dissipation capability of the visco-hyperelastic layer. The material is intended to be used in different ballistic applications such as projectile catching systems and anti-ricochet layers covering walls of shooting ranges, ballistic tunnels.
