Abstract
In this paper, based on the concept of the peripheral surface, a behavioral model for integrated modeling of clay and sand is presented. In this model, the concepts of critical state and state parameter are used. In order to simulate both clay and sand in an integrated manner, a general expansion law is used in this model. This model uses an inhomogeneous flow law and an isotropic hardening law. In order to implement the proposed model, the implicit Euler method based on the recursive mapping algorithm is used. By implementing the model, its efficiency was evaluated by uniform triaxial tests on clay and sand. Therefore, the behavior of clay and sand under uniform drained and undrained triaxial tests was modeled and compared with laboratory data. The simulation results show that the proposed model can adequately predict the soft behavior from elastic to plastic, strain softening behavior, hardening, liquefaction, and phase transition for clay and sand under uniform loading. The results also show that the implicit method can guarantee high accuracy and convergence of the answers.
