Plastic Deformation

Beyond the elastic limit the material undergoes plastic deformation. Unlike elastic deformation, plastic deformation is not recoverable, i.e. the change is permanent.

Ductile materials undergo large plastic deformations and waisting before fracturing; brittle materials undergo very little plastic deformation.
