plastic flow


plastic flow

[′plas·tik ′flō] (physics) Rheological phenomenon in which flowing behavior of the material occurs after the applied stress reaches a critical (yield) value, such as with putty.

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.

plastic flow

The deformation caused by stressing a material beyond its elastic limit. The deformation, or the new shape, remains when the stress is removed.
