Question

The elastic limit point on the stress-strain curve appears?

Answer 1

Elastic Limit( Range):

1. The elastic range is defined as the maximum amount of strain that may be applied to a material before its original form can be recovered.
2. When a force is applied in the elastic range, the material returns to its original form after the force is withdrawn.

Proportional limit:

1. The term "proportionate limit" refers to a point upon that stress-strain curve where stress is linearly proportional to strain.
2. Anywhere along the stress-strain curve, the elastic limit position arises before the proportionality limit point.

Therefore, the elastic limit point on the stress-strain curve appears proportional limit.
