Description of hardening characteristics of sand and its confirmation

  • Received Date: 08 Jun 2006

  • According to the test data of sand with different stress paths in the triaxial compression and triaxial extension condition, plastic volumetric strain, plastic shear strain, hardening parameter of Tsinghua model, plastic work and unified hardening parameter H were chosen as hardening parameter respectively, and then the hardening rules as well as the independence on the stress paths of above hardening parameters were discussed. Based on the yield function of modified cam-clay model, constitutive models which used plastic volumetric strain, plastic work and unified hardening parameter H respectively as hardening parameter were proposed. The validity of unified hardening parameter H on describing the stress-strain properties of sands was confirmed by the triaxial test data of saturated sand from Taklamakan desert.
