Abstract

This study presents theoretical and experimental investigations into the strength-deformation characteristics of sand under cyclic loading. A constitutive relation for expressing the inelastic behaviour of sandy soil is proposed based on experimental data. The theoretical aspects are based on a plasticity theory framework. The effect of non-coaxiality was progressively incorporated in the model and was found to be very effective, particularly for modeling the behaviour of sand during unloading or reverse loading. A comparison between predicted and actual results for undrained cyclic shear tests shows that the dynamic strength-deformation characteristics of sands can be satisfactorily simulated.
