Abstract: A new technique is proposed to develop constitutive models for the drained/undrained creep deformation of normally consolidated clays. Based on the general concept, an explicit constitutive model is presented for the ...

Abstract: A new cap‐type constitutive model is proposed to characterize stress‐strain responses of general pressure‐sensitive materials. The model is noble in the sense that both the failure surface and the yield cap are described ...

Abstract: The paper discusses a rate-dependent constitutive model to describe the creep deformation of rock salts. The model is based on the dislocation-related micromechanisms; the concept of effective ...

Abstract: This paper discusses the application of an internal variable, creep constitutive model, where the concept of piecewise linearity in the effective stress-creep strain rate relationship is utilized. ...
