Public ISBD [article]  inEuropean journal of environmental and civil engineering > Vol. 16 N° 2 (Février 2012) . - pp. 121-140 Titre : Experiments and micromechanical modelling of elastic parameters of a composite geomaterial Type de document : texte imprimé Auteurs : Jolanta Lewandowska, Auteur ; Maciej Pilawski, Auteur Année de publication : 2012 Article en page(s) : pp. 121-140 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Homogenisation Rigidity tensor Triaxial tests Geomaterials Numerical computations Anisotropy Résumé : The aim of this paper is to study the elastic behaviour of a periodic composite geomaterial by applying a micromechanical approach. The macroscopic anisotropic rigidity tensor is computed using the asymptotic expansion homogenisation method. The results are partially validated through the triaxial testing of a composite in which the spheres made of sintered clay are periodically embedded in a matrix (Hostun sand HN38). Good agreement was observed between calculated and measured elastic parameters.
