Brinell hardness Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brinell Hardness = 2*Indentation Load/(pi*Diameter of the indenter*(Diameter of the indenter-sqrt(Diameter of the indenter^2-Diameter of the indentation^2)))
HB = 2*P_load/(pi*D*(D-sqrt(D^2-d^2)))
This formula uses 1 Constants, 1 Functions, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Brinell Hardness - (Measured in Pascal) - Brinell Hardness uses a hard, spherical indenter which is forced into the surface of the metal to be tested.
Indentation Load - (Measured in Newton) - Indentation Load duing the hardness test.
Diameter of the indenter - (Measured in Meter) - Diameter of the indenter used in Brinell hardness test. The units is in millimeter.
Diameter of the indentation - (Measured in Meter) - Diameter of the indentation in Brinell hardness test. The units is in millimeter.

STEP 1: Convert Input(s) to Base Unit

Indentation Load: 5000 Newton --> 5000 Newton No Conversion Required
Diameter of the indenter: 10 Millimeter --> 0.01 Meter (Check conversion here)
Diameter of the indentation: 3 Millimeter --> 0.003 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

HB = 2*P_load/(pi*D*(D-sqrt(D^2-d^2))) --> 2*5000/(pi*0.01*(0.01-sqrt(0.01^2-0.003^2)))

Evaluating ... ...

HB = 691064627.570082

STEP 3: Convert Result to Output's Unit

691064627.570082 Pascal -->70.4689804948816 Kilogram-Force per Square Millimeter (Check conversion here)

FINAL ANSWER

70.4689804948816 ≈ 70.46898 Kilogram-Force per Square Millimeter <-- Brinell Hardness

Brinell Hardness Test

Brinell hardness test utilizes a hard, spherical indenter ( hardened steel or tungsten carbide) which is forced into the surface of the metal to be tested. The diameter of the indenter is 10.00 mm.Standard loads range between 500 and 3000 kg in 500-kg increments; during a test, the load is maintained constant for a specified time (between 10 and 30 s).

How to Calculate Brinell hardness?

Brinell hardness calculator uses Brinell Hardness = 2*Indentation Load/(pi*Diameter of the indenter*(Diameter of the indenter-sqrt(Diameter of the indenter^2-Diameter of the indentation^2))) to calculate the Brinell Hardness, Brinell hardness test utilizes a hard, spherical indenter which is forced into the surface of the metal to be tested. The diameter of the hardened steel (or tungsten carbide) indenter is 10.00 mm. Brinell Hardness is denoted by HB symbol.
