plastic deformation

[′plas·tik ‚dē‚fȯr′mā·shən]
(mechanics)
Permanent change in shape or size of a solid body without fracture resulting from the application of sustained stress beyond the elastic limit.

plastic flow, plastic deformation

The deformation of a plastic material beyond the point of recovery, accompanied by continuing deformation with no further increase in stress; results in a permanent change in shape.

When the temperatures rise, the potential energy increases, the greater the potential energy, the more unstable the system and the more likely the occurrence of plastic deformation.
This process of deformation differs from that of amorphous materials, like polymer films, where there is also a change in the slope of force-distance curves at the moment of the beginning of plastic deformations, but this variation occurs continuously.
