UNIFIED 3D CRITICAL-STATE BOUNDING-SURFACE PLASTICITY MODEL FOR SOILSINCORPORATING CONTINUOUS PLASTIC LOADING UNDER CYCLIC PATHS .2. CALIBRATION AND SIMULATIONS

A systematic calibration procedure for the constitutive model gUTS usi ng conventional triaxial data for all but one of the material constant s is described. Typical ranges for the constants for clay and sand are specified together with default values. When all default values are a dopted, just eight material constants need to be determined (gUTS-lite ). A comprehensive series of 49 simulations on clays, silt and sands i n loose and dense states under a wide range of monotonic and cyclic st ress paths, initial states and drainage conditions provide very satisf actory agreement with experimental results.
