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.

Examine the flow pattern of each part to see if the plastic flow front is coming around on itself, or if there is a hesitation of the flow front in filling a thin section of the part.
The extent of anisotropy induced by plastic flow in polymers has been well documented.
Also Tong has presented a phenomenological theory based on the plastic spin concept, Fourier series and concepts of microscopic polycrystalline plasticity for describing the anisotropic plastic flow of the orthotropic polycrystalline aluminium sheet metals under plane stress [14-15].
The confinement pressure provided by the FRP increases continuously with the lateral strain of concrete because of the linear elastic stress-strain behaviour of FRP, in contrast to steel-confined concrete in which the confining pressure remains constant when the steel is in plastic flow.
