A microstructural model on the link between change in pore size distribution and wetting induced deformation in a compacted silt
(American Society of Civil Engineers (ASCE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe water retention curve expressed in terms of water content or degree of saturation and suction is hysteretic, stress path dependent (on void ratio), and depends on pore network. To properly describe its evolving nature, ... -
Efficient computational homogenization of simple elasto-plastic microstructures using a modified Ritz-Galerkin approach
(CIMNE, 2015)
Comunicació de congrés
Accés obertIn this presentation, a recent work [18] on a fast nonlinear homogenization method for simple microstructures is revised. The degrees of freedom of the approach are defined on shear bands. Moreover, the number of degrees ... -
High-performance model reduction techniques in computational multiscale homogenization
(2014-07-01)
Article
Accés obertA novel model-order reduction technique for the solution of the fine-scale equilibrium problem appearing in computational homogenization is presented. The reduced set of empirical shape functions is obtained using a ... -
Microstructural evaluation of the water sensitivity of clayey rocks
(American Society of Civil Engineers (ASCE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper presents both macroscopic and microstructural evidence of the water sensitivity of a low porosity clayey rock from Northern Spain. Particular emphasis is focused on the effects of water sensitivity at micro level. ... -
Modelling the coupled chemo-hydro-mechanical behavior of structured active clays on basis of quantitative microstructural information
(American Society of Civil Engineers (ASCE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialBecause of their mineralogy, active clays are very sensitive to changes in the type and concentration of species dissolved in the pore water. At a molecular level, this sensitivity can be explained by variations in the ...
