Abstract Many metals and alloys have a stress exponent for the creep rate that is considerably higher than the value of three that is typically predicted by creep recovery models. One example is pure Ni. Creep data from Norman and Duran that are analyzed in the paper give a stress exponent of about seven in the temperature range 0.3–0.55

A Circuit Model of Hysteresis and Creep
IEEE Transactions on Circuits and Systems II: Express Briefs, 2015A circuit architecture that models hysteretic phenomena is proposed. The model is flexible enough to reproduce both rate-independent hysteresis and thermal relaxation effects (creep), commonly observed in many real-world physical systems such as piezoelectric actuators.

Failure-mechanism models for creep and creep rupture
IEEE Transactions on Reliability, 1993This tutorial illustrates design situations where creep and creep rupture of components can compromise system performance over time, thereby acting as a wearout failure mechanism. Polycrystalline materials, such as metals and ceramics, and polymers are treated.

Modelling of Steel Creep at High Temperatures Using an Implicit Creep Model
Key Engineering Materials, 2013The paper presents the numerical procedure for modelling the behaviour of steel structures at high temperatures using a newly developed implicit creep model. This implicit creep model uses the calculated creep strains to modify the material stress-strain curves, thus implicitly taking into account the effect of the developed creep strain.

A model for the creep of concrete
Cement and Concrete Research, 1975Abstract Porosity and density changes were measured for a series of mortar specimens and a series of cement paste specimens subjected to various compressive stress histories during desorption and sorption cycles. It was found that hydration is inhibited by compressive stress.

Abstract The introduction of recovery into the logarithmic (exhaustion) creep model leads to a form of creep curve which accords with the experimental observations. In particular, an approximately cubic transient creep, followed by a steady state creep, are both exhibited.
