Abstract

Biot's theory of coupled mechanical-transport behavior of porous materials is applied in the framework of discrete mesoscale modeling. The contribution presents asymptotic expansion homogenization of the discrete poromechanical model. The macroscale becomes homogeneous and continuous and contains all the coupling effects. In contrast, the microscale is discrete and completely decoupled, separate representative volume elements (RVEs) appear for mechanical and mass transport problems. Linear elastic material behavior is assumed, therefore response of the RVEs can be pre-computed in advance and used repetitively at integration points of the macroscopic model.
