A Comparative Study of the Mechanical Properties of Hierarchical Trabecular Bone with other Approaches and Existing Experimental Data

Abstract:

The bone is a hierarchically structured material with mechanical properties depending on its architecture at all scales. Water plays an important role in the bio-mineralization process and serves as a plasticizer, enhancing the toughness of bone. In this paper, a trabecular bone multiscale model based on finite element analysis was developed to link scales from sub-nanoscopic scale (Microfibril) to sub-microscopic (Lamella) in order to predict the orthotropic properties of bone at different structural level. To identify the orthotropic properties, an inverse identification algorithm is used. Furthermore, the effect of water is incorporated. Good agreement is found between theoretical and experimental results.
