Viscoelasticity - Wikipedia
WebIn materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied.
Viscoelastic Material - an overview | ScienceDirect Topics
WebViscoelastic materials exhibit both elastic and viscous properties. Within the scope of the theory of linear viscoelasticity, the elastic property follows Hooke’s law while viscous properties follow Newton’s laws of viscosity.

WebSep 2, 2021 · Introduction. This document is intended to outline an important aspect of the mechanical response of polymers and polymer-matrix composites: the field of linear viscoelasticity.
WebBasic Elasticity and viscoelasticity. In the physically stressful environment there are three ways in which a material can respond to external forces.

WebJan 1, 2020 · Definition. A wide group of materials, such as metals at high temperatures, polymeric materials, biopolymers, or biological tissues, exhibits gradual deformation and subsequent recovery in time. The response of those materials is dependent upon the stress-strain rate and the temperature itself.
WebIn the range near Tg, the material is midway between the glassy and rubbery regimes. Its response is a combination of viscous fluidity and elastic solidity, and this region is termed “leathery,” or, more technically, “viscoelastic”.

WebIn general, if all of the strain is ultimately recovered when a load is removed from a body, the response is termed viscoelastic, but the term is also used in cases for which sustained loading leads to strains that are not fully recovered.

WebFeb 5, 2012 · In a viscoelastic body, if a certain amount of strain ( γ0) is suddenly developed in a body and henceforth kept constant for a while, the strain rate becomes zero, and the stress goes on changing with time, as the large entangled stretched chain segments will try to rearrange themselves in the viscoelastic body.
Web1. Newton’s law of viscous deformation. Subject to a load, a liquid flows. The amount of deformation is time-dependent and unlimited. When the load is removed, the liquid does not recover its original shape. The liquid has no memory.
