Elastic limit.
Explanation:
The elastic limit is the maximum stress that a material can withstand without undergoing any permanent (plastic) deformation. When the stress is removed below this limit, the material returns to its original shape.
Yield stress → stress at which plastic deformation starts.
Ultimate stress → maximum stress before necking.
Breaking stress → stress at fracture.

Within the elastic limit, the material can bear stress up to a limit and then regain its original size and shape after removing the stress.
