Beyond the elastic limit, what occurs in the material?

Explanation:
Beyond the elastic limit, the material yields and undergoes plastic deformation—the atomic structure rearranges in a way that is not fully reversible. When the load is removed, a permanent deformation, or permanent set, remains because dislocations move and become locked in new positions. Fracture is not the immediate outcome of simply exceeding the elastic limit, and immediate full recovery isn’t possible once plastic flow has begun, while no deformation is obviously incorrect in this region.
