Strain energy

In physics, strain energy is the energy stored by a system undergoing deformation. When the load is removed, strain energy as:
$U = \frac 1 2 V \sigma \epsilon = \frac 1 2 V E \epsilon^2 = \frac 1 2 \frac V E \sigma^2$
where σ is stress, ε is strain, V is volume, and E is Young's modulus:
$E = \frac \sigma \epsilon$
