Question

what is yield limit.​

Answer 1

The yield point is the point on a stress–strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior.

Answer 2

If you observe the stress strain graph after a certain time stress and strain won't be directly proportional

In this region the material does not obey hooke's law but will still regain its orignal shape if the stress is removed

Yield limit is also known as elastic limit
