A Creep-Damage Constitutive Model for Sandstone
Applied Mechanics and Materials, 2012Based on the results obtained by the triaxial creep test, a creep-damage constitutive model for sandstone is presented by using the damage theory and by introducing the concept of “the whole process of damage” into Burgers creep model. The parameters of the model are determined by fitting the creep test data.

The role of the constitutive model in creep crack growth modelling
Engineering Fracture Mechanics, 2015Abstract Although high-temperature material response is known to be history-dependent, many models of creep crack growth assume the history-independent Norton constitutive law. Even so, these models capture the experimentally observed creep crack growth by adjusting only the damage model.

Constitutive Model for Viscoplasticity and Creep
1995The constitutive models for cyclic viscoplasticity are used for inelastic analyses of space crafts, airplanes, nuclear systems and electric packaging. For demand of the larger level of accuracy involved in the implementation of computer codes, the development of the better constitutive equations to describe the material behavior such as viscoplasticity,

A Constitutive Model for Anisotropic Creep Deformation
Journal of Engineering Materials and Technology, 1994Anisotropic creep behavior of polycrystalline metals under repeated stress changes is modeled from a phenomenological point of view. The creep model consists of basic constitutive equations (BCE) and an auxiliary hardening rule (AUX) to enhance the predictive capability of the BCE.

A creep constitutive model with variable parameters for thenardite
Environmental Earth Sciences, 2016Results 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.

Observation-guided constitutive modelling for creeping landslides
Géotechnique, 2016Creeping landslides are common in mountainous areas, causing significant damage to buildings and infrastructure. The major difficulty in modelling of these landslides is the inability of laboratory tests to reproduce adequately the macro behaviour in the creeping soil masses. The proposed approach of observation-guided constitutive modelling addresses

On the constitutive modeling of transient creep in polycrystalline ice
Cold Regions Science and Technology, 1990Abstract The theoretical generality of constitutive models for the transient creep of polycrystalline ice and the ability of such models to represent knowledge derived from experimentation in a physically consistent manner are examined in this paper.

A constitutive creep model for single crystal ice
Mechanics of Materials, 1997Abstract A constitutive creep model for single crystal ice has been formulated based on the experimental results and the mechanism of the multiplication process of mobile dislocations. In this model, the primary mechanism is considered to be the dislocation motion on the basal planes of single crystal ice due to strong creep anisotropy. The preferred
