LOCKHEED STRESS MEMO 53 & 140 mm (5.5") THK 7010/T7651
(OP)
Fellow Stress Engineers:
I am attempting to find mc/I per Lockheed Stress Memo 53 for 140 mm (5.5") thk 7010/T7651 material, but cannot find appropriate curves. Can anyone provide a source?
I have a poor-quality copy of SM 53; to my eye, p. 27 appears to cover similar material up to 2.0" thk. Is it possible to adapt these curves in some fashion? If so how?
Thanks in anticipation...

Failing that, perhaps use an alternative method. Bruhn chap. C3 should work and is (as far as I know) universally accepted.

I have investigated the curves on p. 22 of Lockheed SM 53 as well as those on p. 27 and used the two sets to form upper & lower bounds; there is plenty in hand.
Do you have a clear copy of SM53 that you could make available?
Regards

Both files are equally grungy. The extract is an Acrobat extract, so it should be pixel for pixel with the original (I didn't print the range of pages and scan or anything).

'you still have that SM53 document that you provided StressMan2506? I am also attempting to perform some mc/I in relation to SM88a and could really use it.
thanks
