toughness

a property, frequently applied to materials such as jade, that differs from hardness in that it refers to a resistance to breaking -- i.e., breaking or chipping rather than scratching.

Toughness

Ability of a metal to absorb energy and deform plastically before fracturing. It is usually measured bythe energy absorbed in a notch impact test, but the area under the stress-strain curve in tensile testing is also ameasure of toughness.

Toughness

In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. It is also defined as a material`s resistance to fracture when stressed. Toughness require.

Toughness

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 specimen, as well as the presence of a notch and its acuity.
