Abstract Scope |
The mantis shrimp's club possesses both destructive power and exceptional energy-absorbing properties. It has attracted the interest of researchers seeking to develop protective systems with leap-ahead properties. The club’s unique microstructure includes a tough, fibrous interlayer that exhibits a sinusoidal periodicity. Prior research has primarily focused on mimicking either the material composition or fiber orientation of the mantis shrimp, typically under static loading conditions. Here we merge the club’s sinusoidal interlayer design into a composite microstructure and fabricate it using a dual-material 3D printer. A computational model is developed to reveal the structure’s failure mechanism under low-velocity impact loading. Experimental drop-tower testing is used to validate model predictions. Using this model, we further investigate the structure's response to high-velocity impact and optimize its components for enhanced energy absorption. This work improves our understanding of the shrimp’s crack propagation mechanisms under dynamic loading, enabling the development of better amphibious protective systems. |
