Plasticity (physics)

Plasticity, or plastic deformation, is the ability of a solid material to have a permanent change in shape. In physics and materials science, this is called deformation.  

For example, a solid piece of metal being bent or pounded into a new shape shows plasticity. Permanent changes occur in the material itself. In engineering, the transition from elastic behaviour to plastic behaviour is known as yielding.
