Multiscale modelling of compact bone based on homogenization of double porous medium
Original language description
We present a model of homogenized cortical bone tissue to allow for multiscale modeling of diffusion-deformation phenomenon, which may serve as a basis for deeper understanding of strain generated electric potentials and processes influencing the growthand remodeling in living bone. The heterogeneous structure at the level of osteons with the dual porosity representing the canalicular network is homogenized relying on the Biot theory of the fluid saturated porous medium. The upscaled model describes macroscopic flow in the Haversian porosity induced by bone deformation. The fading memory effects apparent in the homogenized constitutive laws arise due to the microflow in the tissue matrix. The model was implemented in our finite element code.
