Toughness
In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing.[1] 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 load bearing capabilities of materials with flaws.[2] It is also defined as a material's resistance to fracture when stressed.
