Numerical validation of homogenized models for heterogeneous structures
The homogenization approach is employed in modeling of mechanical behavior of heterogeneous media with a periodic microstructure. The size of heterogeneities is characterized by parameter epsilon which tends to zero in the process o...

Multiscale simulation of acoustic waves in homogenized heterogeneous porous media with low and high permeability contrasts
Acoustic behavior of fluid saturated, heterogeneous, rigid porous media which consist of two micro-porous materials with high permeability contrast is studied using a two-scale model based on the homogenization theory. At the mesoscopic leve...

Multiscale modelling of compact bone based on homogenization of double porous medium
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 influencin...

FE multiscale modelling of porous fluid saturated tissues
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 to th...
