Abstract
AbstractComputational homogenization is exploited for the analysis of transient hydro‐mechanically coupled problems subjected to quasistatic loading (consolidation) in micro‐heterogeneous porous solids. The classical approach of first‐order homogenization is adopted in the spatial domain on representative volume elements (RVE), which are introduced in quadrature points in standard fashion. Along with the classical averages, a higher order conservation quantity is obtained. An iterative FE 2‐algorithm is devised for the case of nonlinear permeability and storage coefficients, and it is applied to pore pressure changes in asphalt‐concrete (particle composite). Various parametric studies are carried out, in particular with respect to the influence of the characteristics (size, particle arrangement) of the RVE's. Copyright © 2011 John Wiley & Sons, Ltd.
