Elasticity is defined as the ability of a solid to return to its original shape even after being expanded or contracted. Elasticity is termed as the property of a solid to return to its initial state following deformation. It can also be said that the degree to which this property is exhibited is called elasticity. The ability of a solid to return to its original shape after being subject to strain. Most solid materials display elasticity, up to a load point called the elastic limit; loads higher than this limit cause permanent deformation of the material.
