mid-15c., from tough (adj.) + -ness.

The ability of the metal to absorb energy and to deform plastically during fracture. Toughness values obtained in testing depend upon the test temperature, the rate of loading, the size of the test sp [..]

Toughness is a measure of a material’s ability to resist fracture by absorbing the stress and strain imposed by sudden loading/impact. It tends to improve with increasing temperature.

(n) enduring strength and energy(n) the property of being big and strong(n) the elasticity and hardness of a metal object; its ability to absorb considerable energy before cracking(n) impressive diffi [..]

The ability of a steel to absorb large amounts of energy without being readily damaged.

Property of resisting fracture or distortion. Usually measured by impact test, high impact values indicating high toughness.

Ability of a material to absorb, energy and deform plastically before fracturing. Toughness is proportional to the area under the stress-strain curve from the origin to the breaking point. In metals, [..]

The ability of a material to withstand a sudden impact force.

Toughness is a measure of the way a Material behaves when subjected to mechanical stress. A component's failure is indicated by a crack or fracture/rupture. A tough material supports significant [..]

The ability of a hard finish to resist bending, impacts, or distortion without cracking. The opposite of brittleness.

Toughness is the resistance of a material to fracture or break. It is usually measured in units of energy.

The ability of a material to take bending, impact, etc., without cracking.
