| Abstract Scope |
The equine hoof was studied for inspiration in designing high impact resistant and compressive strength materials. Prior research in the hoof’s energy absorbent properties has spotlighted prominent structures in its assembly that have influenced our bioinspired designs. Equine hooves were first tested under drop tower and compression, using micro-computed tomography to quantify damage. Next, numerous models were designed with varying metrics regarding tubule reinforcement and tubule shape, size, and density gradients. Models were fabricated using multi-material additive manufacturing and their characterization provided a comprehensive understanding of how tubular and gradient features affect fracture. The bioinspired models were tested using drop tower, compact tension, and hopkinson bar, exhibiting behavior similar to the observed phenomena in the hoof. Findings regarding these bioinspired models provide insight into the complexity of the hoof structure.
