Experiments and micromechanical modelling of elastic parameters of a composite geomaterial
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 homogenization 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.
