This article is about toughness of physical objects. For the mathematical concept in graph theory, see Graph toughness.
In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing.[1] Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. This measure of toughness is different from that used for fracture toughness, which describes the capacity of materials to resist fracture.[2] Toughness requires a balance of strength and ductility.[1]
