Abstract: This paper investigates the importance of appropriate calibration of the elastic moduli in models for granular soils used in seismic analyses of geostructures. The critique focuses on calibrating the elastic shear modulus ...

Abstract: A plasticity constitutive model for sands is proposed, which combines a bounding surface framework for large cyclic strains with a Ramberg-Osgood-type hysteretic formulation for relatively smaller strains. The distinction ...

Abstract: This paper aims to show that the addition of lime and lime/cement can significantly improve both the stiffness and the resistance to permanent deformation of clay soils even under adverse, though realistic, curing conditions. ...

Abstract: A sand plasticity constitutive model is presented herein, which accounts for the effect of inherent fabric anisotropy on the mechanical response. The anisotropy associated with particles’ orientation distribution, is ...

Abstract: The effects of sand fabric anisotropy on the response of vertically loaded rigid strip footings were numerically investigated with the use of a bounding surface constitutive model developed within the premises of anisotropic ...

Abstract: According to classical critical state theory (CST) of granular mechanics, two conditions on the stress ratio and void ratio are satisfied when reaching and maintaining a critical state (CS). Therefore, CST dictates the ...
