The variable elastic theory and two versions of Lade's elasto-plastic theory are critically compared in terms of their ability to predict the behaviour of loose and dense sand when subjected to isotropic compression, axisymmetric compression, plane strain and for various stress paths involving unloading and reloading. Only Lade's extended model matched observed behaviour well for all stress paths considered.
