Investigation of the capillary effects toward brain tissue poroelastic properties using asymptotic expansion homogenization

Existing brain model to study brain oedema formation has an assumption of homogeneous brain capillary distribution, despite it is actually normally distributed. In this paper, the assumption is improved by applying asymptotic expansion homogenization (AEH) to a vascularized poroelastic model to obta...
