Stretch denim usually incorporates an elastic component (such as elastane) into the fabric to allow a degree of give in garments.

A prototypical elastic component is a coiled spring.

Springs, which represent the elastic component of a viscoelastic material, obey Hooke's Law:

The spring represents the elastic component of the model's response.

There is however also an important correction to the elastic component of the tunneling current at the onset.

The nuchal ligament is unusual in being a tendon with an elastic component, allowing for stretch.

Unlike purely elastic substances, a viscoelastic substance has an elastic component and a viscous component.

Viscoelastic behavior has elastic and viscous components modeled as linear combinations of springs and dashpots, respectively.

The elastic components, as previously mentioned, can be modeled as springs of elastic constant E, given the formula:

First, an elastic component occurs instantaneously, corresponding to the spring, and relaxes immediately upon release of the stress.
