Good Vibrations Tutorials 4

[Burner2k]

Hello,
I have some rudimentary experience on Vibrations using FE. Mainly I have used Normal Modes/Eigen values to troubleshoot singular/rigid body motion errors in Nastran. I want to get myself more familiarized with different vibrations solutions in Nastran as well as some basic understanding of the physics. Any good tutorial recommendations for both? I would rather have a good tutorial where there is excellent correlation between theory & practice i.e. if a particular mode of vibration (freq response) is applicable, I would like the text/material to explain why & so forth.

I am expecting to continue in aero industry and thus I would prefer material related to that particular industry.

My current employer does not deal with vibrations at all and thus I am unable to find any good reference material. I am slowly working my way through Nastran Dynamic Analysis users guide and it is great but I feel like a material one notch below would be more appropriate for my current state.

Thanks in advance...

Concentrating on vibrational fatigue in your online research could help. It is a lot to take in, but actaully this is where you will end up after your study is complete.

Cool site monkeydog... There are lots of NASA sites and documents
that are directly in-line with aircraft engineering.
I came out of retirement in 2007 to work for Jacobs at NASA-MSFC
but Obama killed the program in 2010 so I'm retired for good.

So they won't take offense to the obvious beach boys joke then. Good I can't leave an open door like that alone.
