WebSep 15, 2016 · Fracture toughness is a measure of the energy required to fracture a material that contains a crack. As a metal's yield strength increases, the amount of stress the metal can support without deforming increases. Alternatively, as yield strength increases, a smaller cross-section of metal is required to support a given load without deforming. 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 frac…
