40818: I would appreciate that very much. Thank you.

My application is not fatigue critical, so stress corrosion cracking is not a concern.
Thanks.

Thanks, 40818. This material is rectangular drawn tubing, as you said.
I have material properties in a generic handbook, but they are not labeled A- or B- or even S-basis.
My understanding of FAR 25.613 is that I need A-basis allowables, or that I have to conduct testing to ascertain the...
Does anyone know of published A-basis allowables for 7075-T6 per WW-T-700/7 ? This material is not listed in the AR-MMPDS-01 (MIL-HDBK-5J).
A vendor has made parts from the above material instead of 7075-T6511 per QQ-A-200/11 as required. Because of lead time issues, we have been asked to...
>>>P (tension-MAX) = (nominal rivet Dia) x (Pi) x (nominal depth of head per spec) x (driving factor) x (FSu from NASM5674) x (Fty/Ftu from any reliable source) x (0.50)<<<
Thanks for clarification, Wil. There's a lot of good thinking here. The 0.50 fudge factor on the end seems a bit...
Thanks, Wil. That's really interesting. I've checked the three books I can find in our office. The 1986 edition has no note at all. In 1989, the note included both 5056 and 1100F rivets, but only mentions 2000 series aluminum. My 1995 edition calls out both 5056 and 1100F, and 2000 and 7000...
Thanks, guys.
Wil:
Not to be pedantic, but the note clearly says not to use 1100F rivets in 2000 or 7000 series aluminum. Should I just interpret this as a mistake? I can think of no reason to prevent the use of 1100 in aluminum. I agree with you 100% on the 5056. Strength is not the issue for...
I have a non-structural application on a 747-400 aircraft where manufacturing has asked us to use 1100-F "A" rivets in place of the 2117-T3 "AD" rivets currently on our drawing.
My Boeing Liaison Engineering handbook from my days at Boeing says (on page 60.2.2) "Avoid using 5056 or 1100F rivets...
Bill McComb's Supplement to Bruhn does have a few things to say. On page A10, he states, "Solid and blind rivets and blind bolts are not allowed in primary tension applications. They are allowed in secondary tension cases such as skins with aerodynamic lift forces or internal pressure...
William F. McCombs, one of the coauthors of the 1965/1973 Bruhn book, has published a new book titled "Engineering Column Analysis - The Analysis of Compression Members." I just received it this week, so this is not a real review, but its content looks very similar in style and quality to the...
Many of you are familiar with the book "Analysis and Design of Flight Vehicle Structures" by E. F. Bruhn, which was published in 1965 and revised in 1973. William F. McCombs, one of the coauthors of that book, published a 110-page supplement in 1998, and that supplement has been mentioned here...
