Composite Crippling
Composite Crippling
(OP)
Hi
I have been trying to use crippling charts for sizing composite frames before any test data become available, first come to mind was Fig 5.7.2.4 in Mil-HDBK-17F. I later found out by plotting against other data in Mil-17 that the curve in Fig 5.7.2.4 is rather unconservative.
Is there any good literature out there published crippling data for composites. Also, what would be a good paper on crippling test setups.
Thanks

RE: Composite Crippling
There is very little data in the literature; I'll look thru my files when I get back to the office. Best bet is probably NASA Langley reports on stiffened panels; try searching the NASA technical reports online.
I can't think of anything published on test setups, but will look for those also.
Regards,
Steve
