Analytical study of induced anisotropy in idealized granular materials / L. Rothenburg in Géotechnique, Vol. 39 N°4 (Decembre 1989) 

Public ISBD [article]  in Géotechnique > Vol. 39 N°4 (Decembre 1989) . - pp. 601 –614 Titre : Analytical study of induced anisotropy in idealized granular materials Type de document : texte imprimé Auteurs : L. Rothenburg, Auteur ; R. J. Bathurst, Auteur Année de publication : 2007 Article en page(s) : pp. 601 –614 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Fabric/structure  of  soils  Granular  materials  Stress  analysis  Statistical  analysis  Shear  strength Résumé : Development of induced anisotropy during shear deformation of plane granular assemblies is inves- tigated by introducing statistical characteristics of fabric and contact forces. The introduced micro-structural parameters are explicitly related to the measure of deviatoric load by considering condi-tions of static equilibrium. Verification of the relationship between parameters of anisotropy, average forces and external loads is presented based on numerical simulation of tests on plane granular assemblies. The physical significance of introduced parameters of microstructure and their evolution during shear deformations is discussed.
