Electrolyte flow through piezoelectric porous media and its application to two-scale cortical bone modeling

Popis výsledku v původním jazyce

Cortical bone is heterogeneous material constituted by multiple material phases at different scale levels. The macroscopically observed phenomena, such as remodeling or regrowth, often originate from the processes associated with the microstructural level. On this scale, the cortical bone tissue consists of a solid bone matrix that exhibits weakly piezoelectric behavior and a lacunar-canalicular network saturated by a bone fluid that is assumed to be an electrolyte solution. We developed a two-scale model of electrolyte flow through the piezoelectric porous media to simulate the behavior of cortical bone tissue by employing the upscaling method. The selected upscaling method enables us to reconstruct responses at the microscopic level from macroscopic fields by virtue of the ”downscaling” procedure.   The behavior of the two-scale model of a single bone osteon under the loading is illustrated by a series of numerical simulations.
