Handbook of Mechanics, Materials, and Structures
The Brinell hardness number is the numerical value of the load or force supplied
divided by this area. If /' is the applied load or force (in kilograms), D is the
diameter of the hardened metallic ball (in millimeters) and d is the diameter of the
...

A Brinell Hardness number (HB) is the result of a static indentation test in which a
hardened steel or tungsten carbide ball is pressed into the sample surface and
the size of the indentation is measured optically. HB is the ratio of the applied ...
