Hi ibrahim,

elastic energy is the energy stored in the deformed system. It is equal to the area under the force deflection diagram. In case of a linear elastic system this amounts to 0.5*F*u, where F is the force and u the displacement in the direction of the force in the deformed system.

When comparing two structural systems with the same loads a smaller elastic energy is equivalent to a stiffer structure.

Best,
