Shear modulus of soils at small strains, G max, is an important parameter in the design of
geo-structures subjected to static and dynamic loading. Numerous models have been …

Shape of soil grains has a major role in the characterization of its behavior. This important
feature has an appreciable impact on all mechanical properties of granular soils. In order to …

This paper presents a numerical investigation about the effect of particle shape on small
strain properties (eg, shear stiffness and Poisson's ratio) of granular soils through 3D …

The strain-dependent dynamic properties of sand are generally described by their relative
density and mean effective stress, while the contribution of other factors, like soil origin …

A series of micro-mechanical tests was carried out in order to investigate the inter-particle
coefficient of friction at the contacts of quartz minerals of Leighton Buzzard sand. For this …

Mixtures of sand and rubber particles were simulated using DEM. Rubber content varied
from 0% to 50%. The numerical samples were sheared in the range of 10− 5–10− 2% of ε 1 …

This study aims to develop several novel machine learning (ML) evolutionary algorithms for
the prediction of small strain shear modulus (G max) of clean sands and sand-fines binary …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

Stiffness of soils at small strains expressed through the small-strain shear modulus is critical
for the evaluation of deformations of geo-structures subjected to a variety of stress states …

Small-strain shear modulus (G 0) is a fundamental property required in dynamic analyses.
For sandy soils, G 0 may be affected strongly by particle characteristics such as uniformity …
