Strain Energy

Strain energy is a fundamental concept in the field of materials science and structural engineering, describing the energy absorbed by a material or structure when it is deformed under load.

Consider a rod fixed at one end and subjected to an axial force at the free end, which induces stress and leads to elongation in the rod. 

As the axial force is increased, the elongation increases. The plot of axial force versus elongation results in a characteristic load-deformation plot.

The work done by the axial force, as the r...
