Rebound hardness
Rebound hardness measures how much a material resists deformation when struck by a moving object, typically an indenter. It gauges the surface's resistance to penetration by bouncing back after impact, which relates to the material's hardness. A higher rebound value indicates a harder surface that resists indentation and recovers quickly after impact, while a lower value suggests a softer, more easily deformable surface. This test is commonly used in industrial settings to quickly assess the hardness of surfaces, such as coatings, asphalt, or concrete, providing a practical indicator of durability and wear resistance.
