A constitutive model of sand with inherent transverse isotropy, considering effects of B values

The objective of this paper is to propose a constitutive model of sand with inherent transverse isotropy taking the effects of b values into consideration, and to verify its validity. In order to apply the proposed constitutive model to initial and boundary value problems, it was implemented in a three–dimensional finite element program code. The proposed constitutive model was developed based on consideration of experimental results and the theory of the multi–surface model. It was verified by comparing the experimental results with the calculations.
