| Abstract Scope |
The emulation of biological structures has emerged as a compelling strategy to enhance the mechanical properties of engineered materials. Among these natural marvels, spicules, intricate cylindrical microstructures, hold particular interest due to their impressive mechanical properties attributed to their layered structure. In this study, utilizing CT scanning, we aim to investigate the impact of this novel structure on crack propagation between layers and its potential in enhancing the toughness of the framework. Through meticulous analysis of CT scan data and fracture mechanics principles, we seek to unravel the underlying mechanisms governing crack propagation within these intricate geometries. Additionally, defects fabricated during the printing process using SLA are also scrutinized to understand their influence on structural integrity. The findings from this investigation are expected to contribute significantly to the advancement of bio-inspired design principles in material engineering, offering insights into the development of tougher and more resilient materials for various applications. |
