How Is Vickers Hardness Test Calculated? The Vickers number (HV) is calculated using the following formula: HV = 1.854(F/D2), with F being the applied load (measured in kilograms-force) and D2 the area of the indentation (measured in square millimetres). How is hardness value calculated? A hardness test is typically performed by pressing a specifically dimensioned

How Do You Calculate Brinell Hardness Number?

How Do You Calculate Brinell Hardness Number? The Brinell hardness number is obtained by dividing the load, in kilograms, by the spherical area of the indentation in square millimetres; this area is a function of the ball diameter and the depth of the indentation. How do you calculate Brinell hardness from tensile strength? As can
