| Abstract: | The granular matter mechanics and the thermomechanical approach to establishing elastic/plastic constitutive model for geomaterials are introduced briefly. The form, mechanical behavior and energy dissipation of force chain and the corresponding strong and weak network are analyzed deeply. On the basis of thermomechanical model for soil, proposed by Collins, the stress and strain characteristic of strong and weak network is re-examined; and proper hypothesis is given. And then the idea and procedure of soil constitutive model with micro and macro incorporation is discussed. |
