Load Transfer in Biomineralized Materials

Collagen-Based Structural Biocomposite: Dentin

*Alix Deymier-Black

High energy X-ray diffraction is being used to investigate load transfer behaviors between the ceramic and proteinaceous phases of dentin.

Collagen-Based Structural Biocomposite: Cortical Bone

The goal of this project is to understand the mechanical properties of bones in different loading and environmental conditions. We use the high-energy synchrotron x-ray diffraction technique to measure the strains in the component phases of bone (ceramic hydroxyapatite and organic collagen), and then correlate it to the macroscopic behavior. The experimental results are then compared to results from finite element modeling simulations.

Modeling of Bone Mechanics

*Fang Yuan

We are creating finite element models of bone structure at collagen fibril level to simulate their mechanical responses and compare with experimental data from synchrotron X-ray diffraction measurement. The detailed strain evolution in different phases of bone and the load transfer between them are studied.
