Elastic potential energy gained by a material under tensile or compressive stress
For strain energy of structures, see Energy principles in structural mechanics. For strain energy of solids, see Strain energy density function.
In physics, the elastic potential energy gained by a wire during elongation with a tensile (stretching) or compressive (contractile) force is called strain energy. For linearly elastic materials, strain energy is:
where σ is stress, ε is strain, V is volume, and E is Young's modulus:
