NASTRAN/FEA GUIDELINES FOR AEROSTRUCTURES? 17

[LIstress]

Can anyone recommend texts/papers/websites/etc that provide guidelines for finite element modeling of aerostructures, preferably with regard to NASTRAN? I've been doing FEA for a long time, but very little of my experience is with aerostructures/boxbeam modeling, analysis, and (especially)the results interpretation for downstream use in detail stress work. From the research I've done so far, it seems the big aero companies (I don't work for one) have their own published guidlines on proper use of NASTRAN; I was wondering if there are more publicly available sources with similar content. The FEA of aerostructures seems like a world all its own (e.g., model your spars with rods and shear panels, include only this much skin, and interpret your output just so, in order to do subsequent detail stress work on web buckling and rib crushing). Hopefully you folks that do this kind of thing for a living (work for FEA group in a big aero company?)will know just what I mean, and point me in the right direction. Thanks all.

I have a set of informal notes which was (supposedly) written by Ian Taig in mid 80-ties.

Advices given there are very practical and I believe that most of them are still valid.

I put file on engineering.com

Enjoy!

I just downloaded the material, and it looks very good indeed. A big star for you--hope it's up there by now. Thanks a lot.
