For small deformations, two important characteristics are observed. First, the object returns to its original shape when the force is removed—that is, the deformation is elastic for small deformations. Second, the size of the deformation is proportional to the force—that is, for small deformations, Hooke’s law is obeyed.

But in the real world, solid bodies do deform somewhat, and we sometimes need to allow for these deformation effects. Elasticity refers to the ability of a material to be deformed somewhat, then return to its original state

In Eq. \(\PageIndex{1}\), the stress \(\sigma\) and elastic modulus \(E\) both have units of \(\mathrm{N} / \mathrm{m}^{2}\); the strain \(\varepsilon\) is dimensionless. In all cases, the stress \(\sigma\) is defined as the force \(F\) applied to the body, divided by the area \(A\) over which the force acts:
