Elasto-plastic model for cemented and pure sand deposits
Abstract The development of a two-surface plasticity model for naturally or artificially cemented sand deposits is presented. For vanishing cohesion the model is capable of simulating the behaviour of pure sand. It is based on the theory of bounding surface plasticity and incorporates a non-associated flow rule and the concept of reflected plastic potential. The model is able to simulate the behaviour of cemented granular soil under monotonic as well as cyclic loading conditions. Numerical examples confirm that the model predicts experimental material behaviour with good accuracy. In addition, a finite element application to the boundary value problem of an earth embankment demonstrates both good performance and better correlation with field observations compared to results from nonlinear elastic analysis.
