Reverse engineering nature : design principles for flexible protection inspired by ancient fish armor of Polypteridae
This thesis is about designing structures that combine the dual functions of mechanical protection and flexibility of motion. The structures are inspired by principles observed in the ganoid squamation (scale assembly) of an ancient fish species called Polypteridae, which first appeared 96 million …
