A Simulation Study of Magnesium Alloy AZ31B Behavior in High-Velocity Impact and Ballistic Limit

Journal of Innovation and Technology, 2022
Magnesium Alloy are made of magnesium combined with different metal elements to improve the physical properties. The elements included were manganese, aluminium, zinc, silicon, copper, zirconium, and rare-earth metals. The magnesium density has been stated to be significantly 35% less than aluminium and significantly 77% less than steel.

The impact of the coupling relationship between projectile size and yarn dimension on the ballistic performance of plain weave fabric

Defence Technology
Aramid fibers, due to their relatively high inter-yarn friction, high strength, high modulus, and other characteristics, have become a typical representative of flexible anti-ballistic materials in modern warfare. Current research on the anti-penetration
