Transverse Shear Flexibility

(1/1)

eric:
Where does the approach listed in the HME Panel Buckling doc for transverse shear flexibility effects (sec 4.3.1, honeycomb) come from?  I'm trying to understand this effect a bit more.  Hexcel HRH-10 has a relatively low shear modulus, thus we see a great sensitivity.  Buckling margins w/ and w/o TSF differ by two orders of magnitude.  My sense is that we may be outside some original considerations for what is typical here.

The only verification I could locate here (slide 9) shows much less sensitivity, though I bet that core had a larger GL & GW.

Thank you.
