Brinell Hardness Formula
The following equation is used to calculate the Brinell Hardness number of materials.
- Where P is the applied load (kg-f)
- D is the diameter of the steel ball ( mm)
- d is the diameter of the indentation caused by the steel ball (mm)
Brinell Hardness Definition
The Brinell Hardness is a test performed on a material that describes the overall hardness of the material based on the indentation left during the test.
Brinell Hardness Example
How to calculate Brinell Hardness?
- First, perform the Brinell Hardness test.
Perform the Brinell Hardness test.
- Next, determine the force.
Measure the force applied.
- Next, determine the diameter of the steel ball.
Measure the diameter of the steel ball.
- Next, determine the diameter of the indentation.
Measure the diameter of the indentation.
- Finally, calculate the Brinell Hardness.
Calculate the Brinell Hardness using the formula above.
Brinell Hardness is a characteristic of a material that describes its hardness through the indentation of a material caused by forcing a steel ball onto the material.
This test is typically performed by placing a small sheet of material beneath a 10mm diameter steel ball and applied a force of 3000 kg to the steel ball.
