The main objective of this research is to examine and model the rostrum (nose) of the paddlefish (Polyodon spathula). Specifically, this experimental study investigates the spatial mechanical properties along with the stress state and strain rate dependence of the cartilaginous structure of the rostrum. A Split-Hopkinson Pressure Bar apparatus was employed for producing compression waves for a strain rate of 100 sec-1. Results from the mechanical tests were also compared to results found in previous experiments. Based on the experiments, the characteristic response of the cartilage is then captured using an internal state variable material model and implemented in a finite element simulation of the rostrum. Simulation results capture the mechanics of the stress distribution throughout the rostrum under various loadings. The findings from this research may have broad applicability in development of novel bio-inspired materials and structures.
