Buckling Analysis - Cantilever Beam
Buckling Analysis - Cantilever Beam
(OP)
Hello,
I have a very generic problem of a cantilever beam with a load at the end and am trying to calculate the critical load. I have calculated the critical load to be about 32,000 psi. When I run the analysis through Pro E Mechanica, the first buckling mode is supposed to occur at about 12,000 psi and the second at about 32,000 psi. Why would my hand calculations have found the second mode instead of the first mode?
Also, if anyone knows of a good place either on the internet or a good book to learn more about buckling, please let me know.(Preferably internet resources)
Thanks in advance for any help anyone can give me!

Also post the ProE mode shapes.
What solution are you using for your hand calculation?
Why are you quoting buckling in terms of psi and not load (lbs)?
If this is a cantilever beam with a transverse load, it is likely to fail in bending, not buckling.

Robert M. Jones, "Buckling of Bars, Plates, and Shells". Search for it on google books, I believe you can read the whole book there.
Timoshenko and Gere, "Theory of Elastic Stability". A paperback reprint came out recently for about $15.
