Abstract Scope |
Highly porous ceramic was quantitatively characterized for the morphological parameters within the 3D volume. The size, shape of the pores as well as their distribution and connectivity, can be evaluated for the property of thermal insulation with the supplementary of modeling and analysis. As a bio-inspirited material, sea urchin spine is composed of bio ceramic and organic substance with a hierarchical structure. The complex 3D volume of a sampled structure was digitalized with the XRT techniques. The meshed 3D volume can be input Finite Element Analyses (FEA) for mechanical test with the 3D global scale. Compression of the real structure model revealed that the stress concentrates along the dense growth rings and dissipates through the strut structures. It implied that the rationally constructed hierarchical structure in nature play an important role in high strength-to-weight property. Its mechanical property might be optimized for potential applications of bone defect repair. |
