| Abstract Scope |
This research proposes to investigate the development of advance materials through biomimicry of the Eastern Box Turtle (Terrapene carolina) shell. The study focuses on replicating the hierarchical structure of the shell including the trabecular interior. The proposed methodology uses finite element analysis to generate predictive computer models, simulating stress distribution and fracture mechanics across the hierarchical interfaces and testing these results through compression and three-point bending tests. By correlating computational models with experimental results, this research aims to establish a design framework for resilient, lightweight protective systems, reverse engineering the box turtle's defense mechanisms into tailored geometries that can vary the mechanical responses load bearing materials. Preliminary data indicates that 3D-printed structures replicating these biological motifs exhibit superior energy absorption compared to monolithic controls. |
