Abstract : The need for a micromechanical approach to modeling the stress-strain response of granular soil is discussed and justified. This work focuses on the small shear strain behavior, and investigates the validity of modeling analytically uniform, rounded-grained quartz and by arrays of identical elastic, rough, quartz spheres. As a first step, the stress-strain properties of six regular arrays of spheres are studied in some detail, with focus on isotropic and biaxial boundary loading. Keywords: Particular mechanics; Regular arrays of spheres; Self consistent method; Stress-strain relationships; Isotropy, Transverse isotropy; Small strains; Threshold strain/P-waves; Shear modulus.
