Brinell Hardness Number Calculator W Formula
Introduction
Calculating the Brinell Hardness Number (BHN) is crucial in material science and engineering to determine the hardness of metallic materials. This article presents a user-friendly calculator to accurately compute the BHN based on the Brinell hardness formula.
How to Use
To use the calculator, simply input the values of the applied force (F), the diameter of the indenter (D), and the diameter of the indentation (d) into the respective fields. Then, click the “Calculate” button to obtain the Brinell Hardness Number (BHN) result.
Formula
The Brinell Hardness Number (BHN) is calculated using the formula:
Where:
- F = Applied Force
- D = Diameter of the Indenter
- d = Diameter of the Indentation
Example Solve
Let’s say we have an applied force of 3000 kgf, an indenter diameter of 10 mm, and an indentation diameter of 2 mm. Plugging these values into the formula, we get:
After computation, the Brinell Hardness Number (BHN) is approximately 374.5.
