Which characteristic of orthodontic wire describe energy storage capacity?
Correct Answer: Resilience
Description: Popularly, the term resilience is associated with springiness, but it means precisely the amount of energy absorbed within a unit volume of a structure when it is stressed to its proportional limit.
The resilience of two or more materials can be compared by observing the areas under the elastic region of their stress-strain plots assuming that they are plotted on the same scale. The material with the larger elastic area has higher resilience.
Key Concept:
Resilience—The amount of elastic energy per unit volume that is sustained on loading and released upon unloading of a test specimen.
