Impact resistance refers to the ability of a material or object to withstand sudden forces or shocks without breaking or deforming. This property is crucial in various applications, such as construction, automotive, and sports equipment, where durability and safety are essential. Materials like steel, plastic, and composite materials are often tested for their impact resistance to ensure they can endure harsh conditions. Testing for impact resistance typically involves dropping a weight from a specific height onto the material and measuring the damage. The results help manufacturers select appropriate materials for their products, ensuring they can handle everyday wear and tear, as well as unexpected impacts.
