摘要:In this lecture, a bio-inspired flexible body armor consisting of two-layer structure composite scales was introduced and analyzed. Finite element analysis was performed using the finite element method package with LS-DYNA commercial software. Results show that the proposed flexible body armor with silicon carbide ceramic exhibits superior bulletproof properties over Al2O3 and B4C ceramics. The impact velocity of the bullet in the vertical direction decreases rapidly with increasing overlapping angle of the scales. The maximum deformation of the bio-inspired flexible body armor decreases with increasing number of Kevlar layers. The frictional coefficient between adjacent scales slightly influences the protective performance of the bio-inspired flexible body armor. This numerical study can provide a basis for designing a novel bio-inspired flexible body armor.
