Prof Andrade will present a simple predictive model for sands. The model is based on critical state soil mechanics (CSSM) and plasticity theory and has been implemented into a general-purpose nonlinear finite element code. I will show the predictive capabilities of the model to capture drained and undrained behavior in sands under a range of relative densities and stress paths. In particular, applications of the model to predict the onset of instabilities such as shear banding and liquefaction will be presented.
