DESCRIPTION: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 e
 lement code. I will show the predictive capabilities of the model to captu
 re drained and undrained behavior in sands under a range of relative densi
 ties and stress paths. In particular\, applications of the model to predic
 t the onset of instabilities such as shear banding and liquefaction will b
 e presented.
