During elastic strain, bonds are stretched but not broken. When the applied stresses are removed, the material ______.

Explanation:
When a material experiences elastic strain, bonds are stretched but not broken, so the deformation is reversible. Once the applied stress is removed, the atoms return to their original positions, and the material goes back to its original shape and dimensions. This recovery is described by Hooke’s law in the elastic region, where stress and strain are proportional and the stored energy is elastic potential energy that is released when the load is removed. If the stress had surpassed the elastic limit, the material would undergo permanent, plastic deformation instead.
