buckling panel

[floch]

Hi all

I look for a general formula to calculate the critical buckling of the sandwich beam.

What do you recommend?

Thanks

There are a number of classic references for looking at sandwich/honeycomb panel analysis. Diab and Hexcel to simple introductory texts. Allen, Zenkert and Bitzer are more thorough. The NASA contractor report may be the best bet. MIL-HDBK-23 is hard to get hold of.
