“…This is because the contact adhesion is not a function of the confining stress and at a higher degree of cementation the contact adhesion has a dominating effect. Similar observations have been made by Chang & Woods (1987) based on experimental results. However, they observe a higher slope of the log Gmax against log u 0 • This discrepancy may be due to the idealization of real sand as an assembly of spherical, topographically smooth, linear elastic particles.…”

Micromechanical modelling of cemented sands under low amplitude oscillations

Microstructural continuum modelling is applied to study the mechanical properties of cemented sands under low amplitude oscillatory loading. The effect of cement in sand is accounted for by considering adhesion in addition to friction at the inter-particle contact. Under the assumption that cemented sands are statistically isotropic random packings of equal spheres, a closed form relationship is derived for the initial shear modulus of cemented sands under isotropic confining stress. Also, the secant moduli and damping ratios are computed numerically for various strain amplitudes. The influence of degree of cementation, initial confining stress, particle size, void ratio and strain amplitude on the mechanical properties of cemented sands are investigated. Comparisons of the theoretically predicted results are made with experimental measurements.
