“…Shafiq [17] systemically studie the dynamic deformation characteristics of zirconium diboride-silicon carbide by multiaxial quasistatic and dynamic compression experiments, the yield strength of confined sample increases to more than four times. Furthermore, the higher the prestress level was, the stronger the erosion of ceramic to projectile, this result was further confirmed by Zhang through ballistic experiment and numerical simulation [18]. Nylon washer and locknut arrangement used to apply prestress onto the frame outside, which enhanced the performance of alumina through much less radial cracks and less the size of the impact crater [19].…”

It is well known that silicon carbide (SiC) ceramic is a pressure dependent material, where the compressive strength increases as the pressure increases. So, it is an effective way to improve the ballistic performance of SiC ceramic by introducing prestress on ceramics surface. In this paper, the concept of dynamic prestress on SiC ceramic by energetic materials was proposed. Five key factors, including the time of projectiles contact targets, velocity of the long rod projectiles (V p), prestress rising stage time (T r), prestress descent stage time (T d) and peak pressure of prestress (P k), were selected to investigate the effect of dynamic prestress on SiC ceramic targets against long rod impact. The effect of dynamic prestress on the ballistic performance of SiC ceramic were investigated, and the dynamic prestress path which can increase the protection capability of SiC ceramic was given. The results indicated that, in most cases, the ballistic performance of the dynamic prestressed SiC ceramic targets against long rod projectiles impact was improved. However, it was also revealed that not all dynamic prestressing can improve the ballistic performance of SiC ceramic targets. It will be benefit to the ballistic performance of SiC ceramic by controlling the prestress time to make sure the moment of the long rod projectile impacts the target in between T 2 and T 4. The sequence of influence degree of each factor on the erosion length of long rod projectile is the velocity of long rod projectiles (V p), prestress descent stage time (T d), peak pressure of prestress (P k) and prestress rising stage time (T r). The erosion length of long rod projectile decreases with the increase of V p, and increases with the increase of prestress descent stage time (T d), peak pressure of prestress (P k) and prestress rising stage time (T r).

This research aims to determine the effect of the panel configuration which has the strongest resistance and to analyze the ballistic toughness of the Al2O3 and Weldox 460 E Steel panel configurations. The criteria to be looked for are the Depth of Penetration, Deflection and Final Projectile Length. To determine the accuracy of this study, a verification of the simulation research previously conducted by Dey et al. The method used is based on simulation with the finite element method. The software used is ANSYS/Explicit Dynamic solver AUTODYN 18.1. The modeling used in this study is simplified into 2D Axisymmetric. Alumina and Weldox 460 E steel panel configuration variations that will be used in this study. There are 7 variations of the panel configuration used, namely B12, A5B5, A5B10, A10B5, A10B10, A12B12 and A15B15. Alumina material as the front panel, while Weldox 460 E as the back panel. In calculating the mechanical behavior of the material, while the Alumina material uses the Johnson Holmquist (JH2) Strength parameter. And then, the Weldox 460 E material uses Johnson and Cook parameters. The results obtained indicate that the A12B12 and A15B15 panel configurations are able to withstand projectiles. The A12B12 panel configuration has a depth of penetration value of 23 mm, a deflection value of 4.3 mm and a Vbl value of 954.69 m/s. while the best panel configuration is A15B15 with a depth of penetration value of 21 mm, a deflection value of 1.4 mm and a Vbl value of 1345.9 m/s. then the conclusion of this study shows that the A15B15 panel configuration is the best panel configuration that is able to withstand projectiles.

Novel body armors are designed to protect against ballistic threats in the most vulnerable organs within the thorax and abdomen. Decreasing the armor weight without affecting its total integrity after the impact is one of the most challenging tasks. In this study, we combine advanced numerical simulations and experimental tests to investigate the ballistic performance of multilayered armor systems (MAS) consisting of laminated alumina (Al2O3) ceramic plates with multi-curve form and a hybrid composite backing. The ballistic trauma absorption and ceramic fracturing morphology are considered evaluation criteria. The investigation provides enough data on the measured trauma and the results are compared to advanced monolithic ceramics. The ballistic tests showed that bonding three or two ceramic plates with polymeric interlayer decreases considerably the eroded ceramic mass in comparison to monolithic ceramic tiles. Furthermore, the layup of two thin Al2O3 tiles with frontal confinement gives the same trauma-weight index as monolithic silicon carbide and reaction-bonded boron carbide plates. The combination of K129 and KM2 aramid weave fabrics decreases the composite backing weight by 33% and increases its ballistic performance in comparison to homogeneous aramid fabrics. Numerical simulations that involve the use of solid Lagrange and adaptive solid/smooth particles hydrodynamics (SPH) numerical approaches with detailed 3D models of the bullet and the MAS are presented in this work. Based on the statistical analysis, a better prediction of the back face deformation and bullet residual length is obtained by the adaptive solid/SPH method, which is found more suitable for the simulation of multilayered armor impact scenarios.
