Abstract

Read online

Nacre structure is used as inspiration in the design of impact resistant materials yet natural nacre is overcome by high impact speed attacks from predators. Here, the authors perform a range of testing and demonstrate superior energy dissipation of nacre-like structures at low impact velocities which is lost at higher impact velocities.
