| Abstract Scope |
This study evaluates the mechanical response of turtle shell-inspired composites, examining how serrated suture presence, scute quantity, and shell height dictate energy absorption. Following morphological characterization via scanning electron microscopy (SEM) and confocal laser scanning microscopy, multi-material 3D-printed turtle shell-inspired models were subjected to quasi-static, drop-weight, and linear motor impact testing actuator (LIMA) dynamic testing to quantify strain-rate sensitivity. Cyclic compression testing was performed to assess stiffness degradation across loading cycles. Fracture path analysis was conducted to investigate crack deflection behavior. Ultimately, empirical equations correlating geometric parameters to specific energy absorption (SEA) were established using the response surface methodology (RSM). Results demonstrate that topological variables and structural profiles critically govern impact resilience, providing a predictive mathematical framework for optimizing turtle shell-inspired structures in protective engineering. |
