| Abstract Scope |
The remarkable static and dynamic properties of biomaterials emerge from a combination of multiscale hierarchical structuring and constituent anisotropy and heterogeneity. While significant progress has been done towards unraveling Nature’s design principles, understanding of the influence of biomaterial structure on elastic wave propagation is still elusive and incomplete. Mechanical characterization has traditionally relied on contact- and deformation-based techniques to access material properties at different length-scales, often translating in invasive and destructive experiments. In this work, we will present the results of a comprehensive and multiscale suite of non-contact, non-destructive ultrasonic characterization experiments that enable access to the MHz-GHz phononic spectrum, attenuation, and even thermal properties of biomineralized materials. Together with continuum modeling results, the present approach provides new insight into the dynamic properties of biomaterials. |
