The Correct Option is C
Solution and Explanation
The work done in producing strain on a material per unit volume is referred to as resilience. Resilience is a property of a material that represents its ability to absorb energy when it is deformed elastically and to release that energy upon unloading. Resilience is defined in terms of the area under the stress-strain curve in the elastic deformation region.
| Concept | Definition |
|---|---|
| Elasticity | The ability of a material to return to its original shape after the stress is removed. |
| Plasticity | The ability of a material to undergo permanent deformation under load. |
| Resilience | The capacity of a material to absorb and release energy within the elastic limit. |
| Creep | The tendency of a material to deform permanently under the influence of mechanical stresses over time. |
