Title: Nonassociated elastic/viscoplastic constitutive equations for sand
Abstract: Elastic/viscoplastic constitutive equations for sands are proposed. Since an associated constitutive equation is unable to fit well the data, a nonassociated constitutive equation is chosen. It is shown how the equation of the stabilization boundary, the viscoplastic potential, and other constitutive parameters can be determined from the data. Failure,, dilatancy, and/or compressibility are included in the constitutive equation. Prediction of the model compares favorably with the experimental evidence.
