GENERAL KNOWLEDGE

Detailed explanation-1: -plasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture (see yield point).

Detailed explanation-2: -The flow rule describes the interconnection between the next plastic strain increment at a stress state for a deformed material point. This relation reminds us of the stress‐strain relation for a viscos fluid and uses the principle of a plastic potential surface g.

Detailed explanation-3: -Plasticity is a mechanical property of materials that shows the ability to deform under stress without breaking while retaining the deformed shape after the load is lifted. Metals with higher plasticity are better for forming. This is evident in metal bending.
