Abstract

A unified plastic modulus parameter for the bounding surface plasticity model is introduced in order to maintain the identical responses of modeling for both the two-dimensional and three-dimensional stress space with the same model parameters. Also discussed are the influences of the plastic modulus parameter on the stress-strain relationship and the plastic modulus. The model is more sensitive in modeling the stress strain responses when the plastic modulus parameter is small. The plastic modulus parameter has a great influence on the magnitude of the plastic modulus, especially at the initial loading stage. The plastic modulus asymptotically tends to zero at the end of loading.
