Question

difference between strain energy and complementary energy

Answer 1

Hi there

Your answer is :

Strain Energy : - 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.


Complimentary Energy : - The area enclosed by the inclined line and the vertical axis is called the complementary strain energy. For a linearly elastic materials the complementary strain energy and elastic strain energy are the same.



Thank You

Answer 2

Complementary energy is the expanse encompassed by the sloping formation, and the upright axis is called the complementary strain energy. For linearly elastic materials, the entire strain energy and elastic strain energy are the same.

But, Strain energy is described as the strength collected in a body due to deformation. The area under the stress-strain curve towards the point of deformation and the strain energy per unit volume is known as strain energy density. When the applied force is discharged, the whole system responds to its initial shape.
