an elastic rebound
The sudden return of an elastically-deformed rock to its original shape when a load is removed or a stress released. This often occurs in earthquakes, as rocks either side of a slip fault, which have been stressed by friction along the fault plane, overcome static friction and rapidly rebound. Elastic rebound must not be confused with isostatic rebound, which is a much slower process in which mantle material flows under pressure into areas under the crust where large loads such as oceans or ice sheets have been removed, thus forcing the crust to rise where the load has been removed and fall elsewhere. Because of the large scales involved and extremely high viscosity of the mantle material, isostatic rebound very slow. The ground surface in the area of Scandinavia is still rebounding at a measurable rate (about 10mm per year) as a result of the melting of the Weichsel ice sheet ten thousand years ago.
Rubber is not reversible in the sense that once it is stretched or deformed, it generally does not return to its original shape. However, rubber can be melted down and reformed into new shapes or products, which is a form of reversible transformation.
No, cellulose is not an elastomer. Cellulose is a structural polysaccharide found in plants that provides rigidity and strength to cell walls. Elastomers are synthetic or natural polymers with elastic properties that can return to their original shape after being stretched or deformed.
The ability to oppose a change in shape is known as elasticity. Objects that exhibit elasticity can return to their original shape after being deformed. This property is commonly observed in materials like rubber bands, springs, and certain metals.
Nitinol's shape memory effect allows it to return to its original shape after being deformed, which makes it suitable for flexible and durable glasses frames. Additionally, nitinol is lightweight and has good corrosion resistance, making it a practical material for glasses.

The sudden return of elastically deformed rock to its original shape may indicate the occurrence of an earthquake or other tectonic activity that released accumulated stress within the rock. This phenomenon is commonly observed in regions with high seismic activity, where rocks experience deformation due to the build-up of strain energy before ultimately rebounding to their undeformed state when stress is released.
This phenomenon is known as elastic rebound. When rocks experiencing elastic deformation reach their limit, they release stored energy and snap back to their original shape, often causing an earthquake. This process is commonly observed along fault lines where tectonic plates meet.
The "elastic portion" is precisely the part where the material returns to its original shape, and thus returns its energy. Once the material does NOT return to its previous shape, it doesn't exert a force back to the original position, and there is no way to get the energy back.

The sudden return of an elastically-deformed rock to its original shape when a load is removed or a stress released.

Elasticity describes the ability of a solid to return to its original shape after being deformed or stretched.
Most materials are elastic - or behave elastically - at least a little bit. This means that when you apply forces to them to deform them, they return to their original size and shape after the deforming forces are removed.
elastic
The linear portion of the stress-strain curve represents the elastic deformation of a material. This is where the material behaves elastically and will return to its original shape once the applied stress is removed.
The sudden return of elastically deformed rock to sit original shape is called elastic rebound. Elastic rebound happens when stress on rock along a fault becomes so grat that the rock breaks or fails. This failure causes the rocks on either side of the fault to jerk past one another. During this sudden motion, large amounts of energy are released. This energy travels through rock as seismic waves. These waves cause earthquakes. The strength of an earthquake is related to the amount of energy that is released during elastic rebound.
No, elasticity is the ability of a material to return to its original shape after being stretched or deformed. If a substance is unable to stretch, it would lack elasticity.
