Elongation of Bolt under Action of Pre Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Elongation of Bolt = Pre Load in Bolt/Stiffness of Bolt
ẟ_b = P_i/k_b'
This formula uses 3 Variables

Variables Used

Elongation of Bolt - (Measured in Meter) - Elongation of Bolt is the difference between the measurement in readings taken before and after tightening a bolt.
Pre Load in Bolt - (Measured in Newton) - Pre Load in Bolt is the tension created in a bolt when it is tightened.
Stiffness of Bolt - (Measured in Newton per Meter) - The Stiffness of Boltt is the extent to which the bolt resists deformation in response to an applied force.

STEP 1: Convert Input(s) to Base Unit

Pre Load in Bolt: 16500 Newton --> 16500 Newton No Conversion Required
Stiffness of Bolt: 317000 Newton per Millimeter --> 317000000 Newton per Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ẟ_b = P_i/k_b' --> 16500/317000000

Evaluating ... ...

ẟ_b = 5.20504731861199E-05

STEP 3: Convert Result to Output's Unit

5.20504731861199E-05 Meter -->0.0520504731861199 Millimeter (Check conversion here)

FINAL ANSWER

0.0520504731861199 ≈ 0.05205 Millimeter <-- Elongation of Bolt

(Calculation completed in 00.004 seconds)

Yield Strength of Bolt in Tension given Tensile Force on Bolt in Shear

LaTeX Go Tensile Yield Strength of Bolt = (2*Tensile Force in Bolt*Factor of Safety of Bolted Joint)/(pi*Core Diameter of Bolt*Height of Nut)

Yield Strength of Bolt in Shear given Tensile Force on Bolt in Shear

LaTeX Go Shear Yield Strength of Bolt = Tensile Force in Bolt*Factor of Safety of Bolted Joint/(pi*Core Diameter of Bolt*Height of Nut)

Yield Strength of Bolt in Tension given Tensile Force on Bolt in Tension

LaTeX Go Tensile Yield Strength of Bolt = 4*Tensile Force in Bolt*Factor of Safety of Bolted Joint/(pi*Core Diameter of Bolt^2)

Maximum Tensile Stress in Bolt

LaTeX Go Maximum Tensile Stress in Bolt = Tensile Force in Bolt/(pi/4*Core Diameter of Bolt^2)

Elongation of Bolt under Action of Pre Load Formula

LaTeX Go

Elongation of Bolt = Pre Load in Bolt/Stiffness of Bolt
ẟ_b = P_i/k_b'

What is Bolt Elongation?

The difference between the measurement in readings taken before and after tightening a bolt is the bolt elongation. For example, before tightening the reading showed 120mm and after tightening showed 121.5mm, it means the bolt was stretched 1.5mm.
