An elastomer, which is also called "a rubber" but most elastomers contain no rubber.
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.
Elasticity is the property of deforming under force and regaining shape when the force is removed.
Elasticity is the ability of a material to return to its original shape after being deformed. It is not a form of energy. Mechanical energy is needed to deform the material which stores this partially as potential (mechanical) energy, some is transformed to heat energy, which dissipates, and some is lost to entropy, as in all energy conversions. When the potential (mechanical) energy is released it can be used to drive an electrical generator to produce electricity, until the material returns to its original shape.
The ability of a material to bounce back after being disturbed is called elasticity. It refers to the ability of a material to regain its original shape and size after deformation or stress is applied to it and then removed. This property is commonly observed in materials like rubber or springs.
On a very small scale, it is true.

Elastic deformation returns to it's original shape after a strain is applied. Plastic deformation returns to a deformed shape after a strain is applied. The material's molecular bonds are strained to the point of fracture, making it not possible to return to the same state. Elastic deformation will return to its original shape. Plastic deformation is when you alter the original form. To understand more on this subject you might investigate failure analysis literature. Lots of good stuff there ratchet marks, beach marks, reverse bending etc... I believe the U.S. metallurgical society has the best reference material on this subject. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape, is called elastic deformation. In other words, elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed. Examples would be the loading of a bridge or building support beam where the loads remain within the original design parameters, or the use of a safety pin where when it is opened it returns to it's unloaded shape. When the stress is sufficient to permanently deform the metal, it is called plastic deformation. Examples would be the building support beams for the twin towers, where the heat generated by the fires decreased the strength of the steel and allowed it to deform plastically, or the loads that are applied to a section of electrical conduit or mechanical piping in order to bend them into a specific shape. in elastic def. , the material returns to its original shape once force is removed. in plastic, the deformation is permanent and the material doesn't return to its original shape the elastic deformation happens in yield point and elastic deformation back to original size but plastic deformation will not back tto original size.

Anelastic deformation. Deformation processes where a material assumes its original shape after the load is removed, but with a time delay.
It depends on the shape of the material removed.

Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.
Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.
If a the stress of a material exceeds the yield stress, it will not be able to return to its original length or shape once the force is removed.
Plastic deformation is a permanent unrecoverable deformation. When the load that caused the deformation is removed, the material will not return to it's original shape but will maintain it's newly deformed shape.
