Material behavior: definition of resilience Choose the correct definition of resilience in strength of materials. Select the correct option.

Difficulty: Easy

Energy stored in a body when strained within elastic limits
Energy stored in a body when strained up to fracture
Maximum strain energy which can be stored in a body
None of the above

Correct Answer: Energy stored in a body when strained within elastic limits

Explanation:

Definitions
Resilience: strain energy stored within the elastic range (per unit volume is modulus of resilience).
Proof resilience: maximum strain energy that can be stored within the elastic limit.

Hence
Option (a) is the correct definition of resilience.

Final Answer
Energy stored in a body when strained within elastic limits
