摘要: Abstract The effect of fabric on low-strain shear stiffness properties granular soils was assessed using Discrete Element simulations. These were idealized as a collection non-spherical particles that interact according to Hertz׳s contact law. Different fabrics the same soil obtained by extracting from weak or strong interparticle force networks. associated evaluated for various levels isotropic triaxial confining stress conditions. conducted analyses showed with given void ratio and level may have noticeably different moduli. mechanical coordination number particle shape found be main factors dictate certain (with specific law). For defined stress, particular is shown linked unique relation.
