Working Principle

The Brinell Hardness Number (BHN) is a measure of the resistance of a material to indentation. It is calculated using the applied load, the diameter of the indentation, and the original diameter of the test piece. The formula used is:

BHN = 0.102 * (P / D^2) * (D - d)

Where:

  • BHN = Brinell Hardness Number
  • P = Applied Load (kgf)
  • D = Specimen Diameter (mm)
  • d = Indentation Diameter (mm)

This calculator helps in determining the hardness of materials by providing a simple and efficient way to compute the Brinell Hardness Number.
