Answer is:
toughness
Explanation:
Toughness:
When a huge external force is applied on a metal, the metal will experience fracture. Toughness is the ability of a metal to resist fracture. The ability of a material to resist fracture due to high impact loads, is called toughness.
Ductility:
Ductility is the property by which a metal can be drawn into thin wires. It is determined by percentage elongation and percentage reduction in area of a metal.
Resilience:
Resilience is the ability of a metal to absorb energy and resist soft and impact load.
Answer is:
fatigue resistance by over-stressing the metal by successively increasing loadings
