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 G
L & G
W.
Thank you.
