Interfacial strength-controlled energy dissipation mechanism and optimization in impact-resistant nacreous structure

Nacre with a combination of superior strength and toughness is one of the best natural body armors due to its unique brick-and-mortar structure, which is recently regarded as the model system for the lightweight and high impact performance composite design. However, most of the studies of nacreous structure focused on static loadings or simple one-dimensional dynamic load. Our study presents 3D finite element simulation, 3D printing and...
