Cosserat 3D anisotropic models of trabecular bone from the homogenisation of the trabecular structure.

The article presents a study which aimed to derive the effective mechanical properties of trabecular bone using a micromechanical approach. The study discussed the homogenisation method for the treatment of elementary cells and internal nodes, which is based on the asymptotic development of static and kinematic variables under consideration. The construction of an anisotropic micropolar for trabecular bone from the homogenisation of the underlying trabecular microstructure is discussed.
