    OverviewPhysicsMeasuring hardnessHardeningFurther readingExternal links

    In solid mechanics, solids generally have three responses to force, depending on the amount of force and the type of material: • They exhibit elasticity—the ability to temporarily change shape, but return to the original shape when the pressure is removed. "Hardness" in the elastic range—a small temporary change in shape for a given force—is known as stiffness in the case of a given object, or a high elastic modulusin the case of a materi
