## What is viscoelastic model?

Viscoelastic behavior has elastic and viscous components modeled as linear combinations of springs and dashpots, respectively. Each model differs in the arrangement of these elements, and all of these viscoelastic models can be equivalently modeled as electrical circuits.

How is viscoelastic material defined?

Being viscoelastic means that the material to some extent both behaves like a liquid and a solid material, and that it has a time-dependent strain.

What is the Kelvin Voigt model for viscoelasticity?

Viscoelastic modelingâ€”passive vibration isolators The Voigt or Kelvinâ€“Voigt model is the simplest viscoelastic model that is very commonly used to model a vibration isolator. This model consists of a spring element and a damping element that are parallel to each other.

### What is the difference between viscoelastic and viscoplastic?

From a rheological perspective, the primary difference between a viscoplastic and viscoelastic material is the presence of a yield stress. A viscoplastic material has a yield stress under which it will not deform, whereas a viscoelastic material will deform at any application of stress.

What is viscoelastic behavior?

Viscoelastic behaviour is a combination of elastic and viscous behaviour where the applied stress results in an instantaneous elastic strain followed by a viscous, time-dependent strain. From: Dielectric Elastomers as Electromechanical Transducers, 2008.

What are the properties of viscoelastic materials?

Dynamic properties of viscoelastic materials are generally recognized on the basis of dynamic modulus, which is also known as the complex modulus. Theoretically, it can be defined as the ratio of stress to strain resulting from an oscillatory load applied under tensile, shear, or compression mode.

#### What is Kelvin Voigt damping?

Definition. The Kelvin-Voigt model, also called the Voigt model, can be represented by a purely viscous damper and purely elastic spring connected in parallel as shown in the picture.

What is spring Dashpot model?

It consists of a spring arranged in series with a dashpot (Figure 1a). This model is known for successfully describing stress relaxation (time-dependent drop in stress under a constant strain) and for failing to describe creep (time-dependent strain relaxation under a constant stress).

What is viscoplastic Behaviour?

Viscoelastic or viscoplastic behavior of a material shows itself in various ways, such as creep under constant load, time-dependent recovery of deformation followed by load removal, stress relaxation under constant deformation, and time-dependent creep rupture.
