| Abstract Scope |
Mantis shrimp are highly aggressive marine crustaceans that employ specialized raptorial appendages known as dactyls for hunting purposes. They also utilize an armor-like segment of their abdomen known as a telson for protection during ritualized fighting. Telsons routinely face high-energy impacts of up to 23 m/s with peak forces up to 1500 N while exhibiting no signs of damage. This study investigates the role of ridged geometries present on the telson and their ability to mitigate stresses observed under high-energy impact events. The study also extends this notion by incorporating such geometries into three-dimensional curved shell structures. Results show that such structures harness a design space where slight modifications of the ridged geometries allow for the control of parameters such as peak loads and dissipated energy without loss to structural stiffness. |
