Explain what impact strength is and give at least one example of the impact strength of a common material.
What will be an ideal response?
Impact strength is the ability of a material to resist a very rapidly applied load, such as the strike of a hammer. It is an indication of the toughness of the material. A material with high impact strength will absorb the energy of impact without fracturing. Impact strength is affected by strength and ductility. Metals that are strong and ductile have high impact strength. Ceramics are strong in compression but are brittle (lack ductility) and break under impact. In general, plastics are very ductile but low in strength and do not absorb impact well.
