The term describing a material's resistance to sudden, high-energy impacts is called?

• A. Impact strength
• B. Hardness
• C. Ductility
• D. Fatigue strength

Answer: (A)

The idea is how well a material can absorb energy when hit suddenly. That property is impact strength. It captures the amount of energy the material can absorb before it fractures under a rapid, high-energy load, which is why tests like Charpy or Izod are used. This is different from hardness (resistance to indentation), ductility (ability to deform plastically), and fatigue strength (resistance to failure under repeated loading). So the term describing resistance to sudden, high-energy impacts is impact strength.
