Numerical study of deformation-induced fluid flows in periodic osteonal matrix under harmonic axial loading

Living bone is a tissue that is constantly renewed. It has been demonstrated that bone fluid flow and induced shear effects on the bone cells are important players in triggering and signaling bone formation and remodelling. This Note presents a model studying interstitial fluid flow in cortical bone under axial harmonic loads. These living tissues are considered as saturated anisotropic poroelastic material characterized by three-dimensional periodic groups of osteons. Using a frequency-domain analysis, the fluid shear stress variations are studied for various loading conditions and geometrical or physical bone matrix parameters. To cite this article: V.-H.
