Abstract: Original Cam-clay model, modified Cam-clay model and a new unified constitutive model for both clay and sand are widely used in both research and engineering applications. Within the classic elastoplastic theory, those constitutive models for geomaterials are deduced afresh in this paper. Comparisons between those constitutive models within the classic elastoplastic theory and the practical geotechnical engineering are made. The relationships between the corresponding variables and parameters are obtained.

Key words: geomaterials, constitutive model, classic elastoplastic theory
