Define strain energy.

Define strain energy.

Right Answer is:

It is the potential energy stored by an elastic body when deformed


Strain Energy

  • When external loads such as forces deform an elastic body they perform work.
  • The work done equals force times displacement in the direction of the force.
  • If the loading is the moment, then the work is moment times the rotation angle.
  • The energy is absorbed in an elastic body because of work done on it by external forces is called elastic strain energy, or just strain energy.
  • Strain energy is the potential energy stored in an elastically deformed body: the energy is equal to the work done (by external forces) in deforming the body.
