Amount of Compression in Parts Joined by Bolt Solution

STEP 0: Pre-Calculation Summary

Formula Used

Amount of Compression of Bolted Joint = Pre Load in Bolt/Combined Stiffness of Bolt
δ_c = P_i/k
This formula uses 3 Variables

Variables Used

Amount of Compression of Bolted Joint - (Measured in Meter) - Amount of Compression of Bolted Joint is the value by which the bolted joint system has been compressed.
Pre Load in Bolt - (Measured in Newton) - Pre Load in Bolt is the tension created in a bolt when it is tightened.
Combined Stiffness of Bolt - (Measured in Newton per Meter) - Combined Stiffness of Bolt is the resisting force per unit change in length of the bolt and the assembly.

STEP 1: Convert Input(s) to Base Unit

Pre Load in Bolt: 16500 Newton --> 16500 Newton No Conversion Required
Combined Stiffness of Bolt: 1500 Newton per Millimeter --> 1500000 Newton per Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δ_c = P_i/k --> 16500/1500000

Evaluating ... ...

δ_c = 0.011

STEP 3: Convert Result to Output's Unit

0.011 Meter -->11 Millimeter (Check conversion here)

FINAL ANSWER

11 Millimeter <-- Amount of Compression of Bolted Joint

(Calculation completed in 00.004 seconds)

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

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

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

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

Factor of Safety given Tensile Force on Bolt in Tension

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

Maximum Tensile Stress in Bolt

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

Primary Shear Force of Eccentrically Loaded Bolted Connection

Go Primary Shear Force on Bolt = Imaginary Force on Bolt/Number of Bolts in Bolted Joint

Amount of Compression in Parts Joined by Bolt

Go Amount of Compression of Bolted Joint = Pre Load in Bolt/Combined Stiffness of Bolt

Elongation of Bolt under Action of Pre Load

Go Elongation of Bolt = Pre Load in Bolt/Stiffness of Bolt

Amount of Compression in Parts Joined by Bolt Formula

Amount of Compression of Bolted Joint = Pre Load in Bolt/Combined Stiffness of Bolt
δ_c = P_i/k

What is the difference between Elongation and Compression?

Deformation is the change in the shape or dimensions of a body under the application of load, whereas Elongation is the change in length of the body under the application of load. So elongation is a form of deformation, but deformation needs not just be elongation alone.
