| Abstract: | To study different working conditions on the impact resistance of ZK61m magnesium alloy thin plate, includes radius of curvature of the projectile (Caliber-radius-head, CRH) and number of layers in the target plate. The impact resistance of magnesium alloy plate by the shape of the projectile head was analyzed through experiments and simulations, the ballistic limit (BLV) of the target plate and the failure mode of the target plate under different CRH projectile impacts were obtained. The experimental results show that the BLV of the target plate decreases with the increase of CRH value and the failure mode changes from shear punch plug failure to tensile cracking failure. The numerical simulation results show that the Lode parameter dependent MMC fracture criterion is closer to the experimental results; the MMC fracture criterion was selected to analyze the effects of CRH and the number of target plate layers on the impact resistance of magnesium alloy thin plates. It was found that the impact resistance of the target plate changes slowly and then increases rapidly with the increase of the CRH value; its impact resistance showed a linear decrease with the number of target plate layers increase.
