Question

What is elastic after effect and elastic fatigue?

Answer 1

Elastic after effect = The delay of certain substances in regaining their original shape after being deformed within their elastic limits.

Elastic fatigue= The temporary loss of elastic properties because of the action of repeated alternating deforming force is called elastic fatigue.

Answer 2

Answer with Explanation :-

Elastic After Effect :-

• When a elastic material is stretched and applied deforming force is removed then it take some time to return to its original shape and size.

• The time taken by materials to regain their original shape and size after deforming force is removed, is termed as elastic after effect.

• The elastic after effect is short for quartz fibre and more for glass fibre.

Elastic Fatigue :-

• The temperory loss in strength of a material due to repeated loading and unloading of stress, is termed as elastic fatigue.

• when a wire is bent number of times at the same point, it cracks and finally breaks.

• The wire is said to be in the state of elastic fatigue.
