摘要

To investigate the dynamic mechanical response characteristics of SiC ceramic/ultra-high molecular weight polyethylene (UHMWPE) composite ballistic plates under the high-speed impact of projectiles, this study established a mirrored 3D-DIC high-speed photography system and validated the accuracy of the system. The accuracy verification showed that the average maximum relative errors in the X, Y, and Z directions were only 0.688%. Additionally, ballistic tests were performed using Type 53 7.62 mm enhanced-charge armor-piercing incendiary (API) projectiles impact on the NIJ IV ballistic plates. The maximum bulge height of the ballistic plate obtained from mirrored DIC analysis was compared with side-view high-speed photography results, showing a maximum error of 1.71%. The results revealed that the ballistic plates bulge reached a maximum value of 36.20 mm at 1100 μ $\mu $ s. The ballistic plate was divided into four regions, and during impact, fibers were stretched along the orthogonal layup directions. The strain field exhibited an L-shaped distribution in each region, with a peak strain of 0.273 occurring at the corners. The mirrored 3D-DIC system of this study accurately measures the deformation of ballistic plates under high velocity impact of projectiles and provides a safer test method for measuring material strains under high speed impact conditions.
