Question

define strain energyand derive the quaction for the same.

Answer 1

Answer:

Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. ... Regarding young's modulus E, the strain energy formula is given as, U = σ2 / 2E × V.

Answer 2

Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
