Mechanical Engineering - Strength of Materials - Discussion

Resilience is strain energy stored per unit volume.

Because we all know that when a material is subjected to an external loading internal resisting forces start developing in a material gradually along with the deformation. As the resisting forces moves with the deformation, work is done by these forces.

This work done is stored as Energy and this energy makes the material to regain its size and shape if the loading is within an elastic limit. This stored energy in a body due to straining of a material is what we call as Strain energy and this strain energy per unit volume is called as RESILIENCE. !

The maximum strain energy that can be stored in a material within elastic limit is Proof resilience. Proof resilience per unit volume is called as Modulus of resilience. !

Thank you:).

Answer is none of the above.

Because resilience is the ABILITY of the material to absorb strain energy not the energy absorbed as many of my friends above have pointed out.

Strain energy stored per unit volume is called resilience.

It is a property of spring.

When a body is subjected to an external force, stress and strain are produced in the body and the work done on the body is absorbed as strain energy in the body.

If the external forces are removed then strain energy absorbed is fully recovered, and it is said to be resilience of the body.

Within the elastic limit, the strain energy is fully recoverable i.e., strain energy= resilience (within the elastic limit).

Resilience is the amount of energy stored per unit volume within the elastic limit.

Where as strain energy is the energy stored in the material within the elastic limit.

Resilience is energy absorption capacity of the component in the elastic region.

Resilience is the property not the amount of stored energy so answer is right.

Resilience is the total strain energy stored in a body.

It is amount of internal energy stored in a body it can say resilience or be strain energy.
