Pretension needed to prevent separation

Pretension needed to prevent separation

Pretension needed to prevent separation

(OP)
Could anyone recommend a reliable resource/text book/software package that would allow me to analyze a bolted joint to determine the amount of pretension required to prevent separation for a given load?

RE: Pretension needed to prevent separation

VDI 2230 Systematic Calculation of Bolted Joints is the most comprehensive source for this type of information.  Software such as SR1 from Hexagon has been created based on VDI 2230.  Perform a keyword search of Eng-Tips for a sampling of problems that have been previously discussed on this subject.  The following are links to the Beuth and Hexagon websites from which you can obtain VDI 2230 and SR1, respectively.

RE: Pretension needed to prevent separation

Some possibiltities:

I use most of the times:FED-STD-H28/2B (1994)
"Federal Standard
Screw-thread standards for Federal Services
Section 2"
Appendix B is a Design method of Unified Screw Threads.

You could also try Mike Niu's Airframe Stress Analysis and Sizing

Or the Fokker Stress Handbook TH3.561 might be used (proprietary document).

RE: Pretension needed to prevent separation

I concur with TVP regarding VDI 2230.  SR1 from Hexagon is good, and here are some other software packages worth considering:

As far as books go, here are the best ones:

Handbook of Bolts and Bolted Joints edited by Bickford and Nassar

An Introduction to the Design and Behavior of Bolted Joints by Bickford

Both books are published by Dekker/Taylor and Francis:
