Load given Brinell Hardness Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Load = (Brinell Hardness Number*pi*Steel Ball Diameter*(Steel Ball Diameter-sqrt(Steel Ball Diameter^2-Depression Diameter^2)))/2
W_load = (BHN*pi*D*(D-sqrt(D^2-d^2)))/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

Load - (Measured in Newton) - Load is the instantaneous load applied perpendicular to the specimen cross section.
Brinell Hardness Number - The Brinell Hardness Number is a number expressing the load applied in testing in kilograms divided by the spherical area of indentation produced in the specimen in square millimetres.
Steel Ball Diameter - (Measured in Meter) - Steel Ball Diameter is defined as a straight line that goes from one side to the other of a circle, passing through the centre.
Depression Diameter - (Measured in Meter) - Depression Diameter is diameter of the depression caused by steel ball.

STEP 1: Convert Input(s) to Base Unit

Brinell Hardness Number: 425 --> No Conversion Required
Steel Ball Diameter: 160 Millimeter --> 0.16 Meter (Check conversion here)
Depression Diameter: 20 Millimeter --> 0.02 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_load = (BHN*pi*D*(D-sqrt(D^2-d^2)))/2 --> (425*pi*0.16*(0.16-sqrt(0.16^2-0.02^2)))/2

Evaluating ... ...

W_load = 0.134043356113669

STEP 3: Convert Result to Output's Unit

0.134043356113669 Newton -->0.000134043356113669 Kilonewton (Check conversion here)

FINAL ANSWER

0.000134043356113669 ≈ 0.000134 Kilonewton <-- Load

Load given Brinell Hardness Number

Go Load = (Brinell Hardness Number*pi*Steel Ball Diameter*(Steel Ball Diameter-sqrt(Steel Ball Diameter^2-Depression Diameter^2)))/2

Total Extension given Area of Mild Steel bar

Go Total Extension = Coefficient of Elongation*sqrt(Cross-sectional Area of Specimen)+(Coefficient of Extension*Initial Length)

Percentage Elongation of Mild Steel Test Bar

Go Percentage Elongation = ((Initial Length-Length of Test Bar at Fracture)/Length of Test Bar at Fracture)*100

Local extension of mild steel bar

Go Local Extension = Coefficient of Elongation*sqrt(Cross-sectional Area of Specimen)

Original Length of Mild Steel test bar given Total Extension

Go Initial Length = (Total Extension-Total Elongation)/Coefficient of Extension

Total Extension of Mild Steel Test Bar

Go Total Extension = Total Elongation+Coefficient of Extension*Initial Length

Area of Mild Steel bar given Local Extension

Go Cross-sectional Area of Specimen = (Local Extension/Coefficient of Elongation)^2

Gross area design strength for steel

Go Design Strength = Gross Area of Cross-Section*Yield Strength/1.1

Load given Brinell Hardness Number Formula

Load = (Brinell Hardness Number*pi*Steel Ball Diameter*(Steel Ball Diameter-sqrt(Steel Ball Diameter^2-Depression Diameter^2)))/2
W_load = (BHN*pi*D*(D-sqrt(D^2-d^2)))/2

What is brinell hardness number?

Brinell hardness number is the hardness of a metal or alloy measured by hydraulically pressing a hard ball under a standard load into the specimen.

How load selection is done in Brinell hardness test Why?

In order to determine the Brinell hardness (HBW) according to ISO 6506, the spherical, hard metal (tungsten carbide) indenter is pressed into a specimen (workpiece) with a defined test load (between 1 kgf and 3000 kgf).
