Description
  • We issue the multiscale modelling of the coupled diffusion-deformation processes in biological tissues with applications in describing blood perfusion, or fluid filtration phenomena in general. Such modelling should allow for revealing some phenomena associated to damage mechanisms in kidney tissue induced by shock wave loading (accidents or medical treatment by lithotripsy). The micromodel to be homogenized is based on the Biot type model for the incompressible medium. Due to the strong heterogeneity in the permeability coefficients associated with three compartments of the representative microstructural cell (RMC), the homogenization of the model leads to the double diffusion phenomena. The model is illustrated on 2D examples which demonstrate capability of the two-scale modelling using the finite element method.

  • Uvádíme víceškálové modelování spojených difůzně-deformačních procesů v biologických tkáních s aplikacemi na popis perfuze krve, nebo obecně filtrování tekutiny. Takové modelování umožňuje odhalit některé jevy spojené s mechanismy poškození ve tkáni ledvin vyvolanými náhlým rázovým zatížením (nehody, nebo léčba pomocí litotrypse). Mikromodel určený k homogenizaci je založen na Biotově modelu nestlačitelného média. Kvůli silné heterogenitě koeficientů permeability ve třech kompartmentech reprezentativní buňky mikrostruktury (RMC), homogenizace modelu vede k jevu dvojité difuze. Model je vysvětlen na 2D příkladech demonstrujících schopnost dvouškálového modelování metodou ko (cs)
