A Rate Dependent Constitutive Model for Clay
The paper presents a strain-rate dependent plastic constitutive model for clays. Based on the concepts of critical-state soil mechanics and bounding surface plasticity theory, the model reproduces the mechanical response of clays under triaxial loading conditions and predicts both the drained and undrained behavior. The model parameters are determined for Boston Blue Clay, London Clay and Kaolin Clay, and the performance of the model in simulating the mechanical response of these clays is demonstrated for low to medium strain rates. In order to determine the effect of the uncertainties associated with predicting the model parameters on the predicted undrained shear strength of clay, a probabilistic analysis using Monte Carlo simulations is performed by treating the model parameters as random variables.
