In the elastic range, stress divided by strain becomes a positive proportional relationship, satisfying Hooke’s law, and its ratio is the elastic modulus. Elastic modulus is an inherent property ... In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. 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 fract…
