Experimental and Numerical Simulation Study of Dynamic Mechanical Behavior of AlMgB14 Ceramic

This study investigates the dynamic mechanical behavior of AlMgB14 ceramic through a combination of experiments and numerical simulations. Firstly, a DOP numerical simulation model of AlMgB14 ceramic is established using LS-DYNA software and compared with experimental results to verify the rationality of the constitutive parameters of AlMgB14 ceramic. Based on this, an anti-penetration model of a composite target plate is established, and the penetration resistance process of the target plate, deformation of the projectile, formation of the ceramic cone, and the effect of ceramic plate thickness on the ceramic cone are analyzed in detail. The results show that the deformation of the projectile mainly occurs during the penetration stage of the ceramic panel. Additionally, the thickness of the ceramic plate has a significant influence on the formation of the ceramic cone. Thicker ceramic plates are less likely to form complete ceramic cones, while thinner ceramic plates hardly form ceramic cones at all. Furthermore, the energy absorption efficiency of the ceramic plate is not positively correlated with its thickness. These findings provide a valuable reference for designing high-performance protective equipment made from composite materials.
