viscoelastic creep occurs during linear viscoelasticity stretching.
viscoelastic creep occurs during linear viscoelasticity stretching.
during which type of stretching does viscoelastic creep occur?
linear viscoelasticity
extreme cold temperatures can cause viscoelastic materials to change to the glass phase and become brittle. for example, exposure of pressure sensitive adhesives to extreme cold (dry ice, freeze spray, etc.) causes them to lose their tack, resulting in debonding.

when subjected to a step constant stress, viscoelastic materials experience a time-dependent increase in strain. this phenomenon is known as viscoelastic creep.
viscoelasticity
viscoelastic creep data can be presented in one of two ways. total strain can be plotted as a function of time for a given temperature or temperatures. below a critical value of applied stress, a material may exhibit linear viscoelasticity. above this critical stress, the creep rate grows disproportionately faster. the second way of graphically presenting viscoelastic creep in a material is by plotting the creep modulus (constant applied stress divided by total strain at a particular time) as a function of time. below its critical stress, the viscoelastic creep modulus is independent of stress applied. a family of curves describing strain versus time response to various applied stress may be represented by a single viscoelastic creep modulus versus time curve if the applied stresses are below the material's critical stress value.
