A creep constitutive model with variable parameters for thenardite

Environmental Earth Sciences, 2016
Results from the triaxial creep tests indicate that the relationship between steady creep rate of thenardite and deviatoric stress can be described with the Heard model. By combining the Kelvin model which reflects the primary creep property of rock with the Heard steady creep model, a Kelvin–Heard (K-H) creep model is constructed.

A constitutive model of granite shear creep under moisture

Journal of Earth Science, 2016
Previous constitutive models of granite shear creep have two limitations: (1) although moisture greatly affects granite shear creep behavior, currently there are no constitutive models that include this factor; (2) there are also no models that include an acceleration stage.

A Constitutive Model for Metals Subjected to Cyclic Creep

Journal of Engineering Materials and Technology, 1991
This paper presents a constitutive model which can be used to predict creep strains and rupture lives of engineering materials undergoing entire creep process, including primary, secondary, and tertiary stages. The model is constructed on the basis of two evolution rules: (1) the continuum damage evolution, and (2) the evolution of internal stresses ...
