Homogenization of flow in double-porous solids with applications in biomechanics
Original language description
In the paper we report on the homogenization based modeling of the deformation induced microflow in cortical bone tissue. Due to porous structure of the cortical bone, any dynamic mechanical loading causes fluid flow through the hierarchy of pores arranged in the bone units called osteons. These are distributed almost periodically and involve pores of different size; from the Haversian canal forming the axis of each osteon the fluid can enter the system of lacuno-canalicular porosities draining the mineralized matrix, which presents the dual porosity. Due to the multiscale modeling approach we can pursue the relationships between macroscopic loading of bone and the stress and microflow localisation in the bone ultrastructure

HOMOGENIZACE PROUDĚNÍ V DUÁLNĚ POREZNÍCH MÉDIÍCH S APLIKACEMI V BIOMECHANICE
Czech description
Článek popisuje využití homogenizace pro modelování kostních tkání v kontextu interakce proudění s pevnými složkami na úrovni mikrostruktury. Homogenizace vychází z Biotova modelu tekutinou nasyceného média, předpokládá se periodicita struktury pórů a škálově závislá permeabilita v duálně porézní oblasti mikrostruktury (lacuno-canalicular porosities)
