Abstract

Abstract: 5.8 mm bullet penetration NIJ Ⅲ grade SiC/UHMWPE body armor was test to analyze the transient mechanical response of body armor and the degree of blunt injury of human chest under non-penetrating ballistic impact. 3D digital image correlation technology (3D-DIC) was used to capture the back face deformation (BFD) of body armor, and the deformation height and speed were obtained. The blunt criterion (BC) and abbreviated injury scale (AIS) were used to evaluate the degree of blunt injury when the distance between body armor and chest was 5 mm and 10 mm, respectively. The test results show that the average maximum height of BFD is 22.7 mm, its average maximum static height is 16.3 mm, and its average maximum deformation velocity is 117.7 m/s. When the gap between body armor and chest is 5 mm, the corresponding AIS level is 4-5, indicating that the blunt effect behind body armor can cause serious injury to the human body. However, when the gap expands to 10 mm, the AIS level is less than 3, indicating that the blunt effect after body armor causes slight injury to the human body and even has no affect on the human body.
