1. Toughness
   In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing; Material toughness is defined as the amount of energy per volume that a material can absorb before rupturing. It is also defined as the resistance to fracture of a...

2. 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.

5. 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.
