| Abstract Scope |
This work presents the results of a combined experimental and computational study on the composition-structure-property relationships in bone at multiple length scales. The mechanical properties of ultrastructure of bone were measured using atomic force microscopy (AFM). The heterogeneity in the composition and elemental distribution across lamellae was investigated using Raman spectroscopy and scanning electron microscopy (SEM). The correlations between the composition, structure, properties were presented. The fracture behaviors of bone were investigated using mechanical testing coupled with micro-CT and SEM. Numerical models were built to simulate the deformation, damage and fracture in bone and to demonstrate the relationship between the fracture behavior and the underlying micro- and nano-structures. Fracture toughening mechanisms across several length scales were revealed through experimental and computational results. The results contribute to new understanding of bone mechanics and micro- and nano-structures. The findings offer prospects for bioinspired design of robust materials. |
