strain energy definition
For strain energy of structures, see Energy principles in structural mechanics. For strain energy of solids, see Strain energy density function. In physics, strain energy is the energy stored by a system undergoing deformation.When the load is removed, strain energy as : where Ï is stress, Îµ is strain, V is volume, and E is Young's modulus :n physics, strain energy is the energy stored by a system undergoing deformation.
