Numerical simulation of ballistic impact behavior of bio-inspired scale-like protection system

The teleost fish scales, such as Grass Carp and Cyprinoid, characterize hierarchical structure which usually consists of a hard bony outer layer and a soft inner cross-ply of collagen fibrils. Each scale overlaps with other neighboring scales, thus fish skin can effectively disperse external loadings with superior flexibility. Inspired by the two-layer structure and overlapping pattern of fish scales, bio-inspired composite scale, and scale-like...
