The smashing Mantis Shrimp has been known for its heavily smashing blow creating the velocity and acceleration equivalent to a .22 caliber bullet with the forces up to 1.5 kilonewtons and the load-bearing part of its raptorial appendages, so-called dactyl club, having a capability of withstanding such tremendous forces. The focus of this research is on this extraordinary damage tolerant dactyl club. We carry out a combined analytical, computational and experimental investigation of the structure-function relationship of two critical regions of the dactyl club that exhibit unique architectures. The inner periodic region contains mainly a “flat” Bouligand structure (mineralized fiber layers stacked in a helicoidal arrangement); whereas the impact region reveals a sinusoidally-architectured Bouligand structure. This new type of architecture was found to be much more impact resistant than the flat Bouligand structure. Our investigation is mainly focused on the mechanics of these two different regions under different loading conditions.
