What is plasticity?

To determine

The plasticity.

Explanation of Solution

When a material is subjected to some external load, for which there is no regain in original shape and some permanent deformation in the shape is caused, then the body is said to have property of plasticity.

In other words, the plasticity is the property of solid that defines the ability to cause any permanent strain by the body at a load applied on the body beyond the elastic limit. Most of the metallic substances undergo permanent change in shape without undergoing any appreciable change in their properties. Thus, plasticity is an important process in metal forming where the material changes shape to solid phase only.
