Yield Strength

If we look at the yield strength meaning: it can be defined as the minimum amount of force that is needed to deform something permanently. It can also be defined as a “measure of the strength of an object”. The deformation caused by yield strength is irreversible, which means the material can not be back into its previous shape. Which is also a basic difference between yield strength and tensile strength. Moreover, the stress which is applied in yield stress is minimum. Another term related to yield stress is used in Physics, known as “Elastic Limit”.Before reaching the yield strength, damage which is caused to a material can be reversed, which is called elastic deformation. But after the elastic limit is reached, the damage is beyond repair, and it is called plastic deformation.
