Spletmodulus from A hardness of 80 down to 20, though some have considered it of less value below a hardness of 40A. Other equations have also been postulated by Ruess such as²: … SpletHardness is a measure of how well a solid material resists permanent shape change when a compressive force is applied. Hardness is dependant on many factors including strength of intermolecular bonds, ductility, elastic stiffness, plasticity, strain, strength, toughness, and many more. Measuring Hardness
