Let $\BB$ be subjected to stress which takes the stress-strain diagram out of the elastic region and into the plastic region.

When the stress is removed, and $\BB$ no longer returns to its original shape, its deformed shape is known as a permanent set.

$OF$ represents the permanent set of $\BB$ after it has been subjected to the stress which has been removed at point $C$.
