What is elastic after effect ?

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.

Also the question is, what is elastic after effect what is its importance? Elastic after effect helps us to know about the elastic behaviour and the elastic property of a material . Now if a material has high elastic after effect then the material is less elastic and if the material has less elastic after effect then the material is more elastic in nature .

In this regard, what is meant by elastic fatigue? The property of an elastic body by virtue of which its behaviour becomes less elastic under the action of repeated alternating deforming force is called elastic fatigue.

You asked, what happens when elastic limit is exceeded? Once a material is stressed to a point exceeding its elastic limit, it begins to permanently yield, and when the stress is removed the material will not fully return to its original length.

Moreover, what do you mean by elastic limit? elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape.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.

What is elastic after effect physics class 11?

What is ‘elastic after effect’? When deforming forces are removed, the body takes time to come back to its original state. The delay in coming back to it’s original state is called ‘elastic after effect’.

What is importance of elastic fatigue?

It is the temporary loss of elastic properties because of the action of a repeated alternating deforming force. For example, bridges are frequently and constantly used. Hence, they are under every second stress which causes elastic fatigue less in steel. Therefore, bridges are affirmed treacherous for extended use.

What is elastic hysteresis in physics?

Elastic Hysteresis is the difference between the strain energy required to generate a given stress in a material, and the material’s elastic energy at that stress. This energy is dissipated as internal friction (heat) in a material during one cycle of testing (loading and unloading).

What causes elastic hysteresis?

The elastic hysteresis is caused due to the difference between the strain energy required to generate the given stress in the material to the material’s elastic energy at the given stress.

When elastic limit the stress is?

Within elastic limit, the stress developed is directly proportional to the strain produced in a body.

What happens when bodies are deformed beyond the elastic limit?

Stresses beyond the elastic limit cause a material to yield or flow. For such materials the elastic limit marks the end of elastic behaviour and the beginning of plastic behaviour. For most brittle materials, stresses beyond the elastic limit result in fracture with almost no plastic deformation.

How is elastic limit determined?

The elastic limit can be determined by measuring the greatest stress that can be applied to a given sample without causing any permanent deformation. For metals or any other rigid materials have the stress-strain curve as a straight line as the elastic limit is approximately equal to the proportional limit.

What is elastic material?

What are elastic materials? Elasticity is the tendency of solid materials to return to their original shape after forces are applied on them. When the forces are removed, the object will return to its initial shape and size if the material is elastic.

What is elastic point?

The point at which the material under the load(say tension) begins to undergo permanent offset is known as elastic limit. Material subjected to the stress below the elastic limit will return to its original shape as soon as the load is removed.

What is elastic fatigue Class 11?

Elastic fatigue happens when a body is subjected to repeated strains or deforming forces, even within elastic limits. Under such circumstances a body loses its property of elasticity.
