Thank you all for your input. I made sure that the problem was fully looked into, and luckily the installation of heat treated E rivets turned out to be an isolated occurence. There was only a few of the bad rivets sprinkled in one row of fasteners, and they were replaced.
Apparently, it is not...
We have had a batch of E rivets (7050-T73) that have been supplied in bags labelled DD. The E rivets have then been mixed up with the DD rivets. The result is that a bunch of E rivets have been heat treated and installed as per the DD procedure. From everything I have read, E rivets are not...
G'day rb1957
Another Aussie huh? Are you in Oz or are you off contracting overseas somewhere?
I agree that before gapping occurs, the fastener preload would allow the moment to be taken on opposite sides of the head or tail, which would result in a pretty much constant tension in the bolt...
Hi Fstress
I don't know if you are interested in the fastener bending aspect of filler analysis, but if you find any methods of fastener bending analysis during your research I would be grateful if you could contribute to a thread I recently started entitled "Fastener Bending Analysis Using...
Thanks for your response rb1957
I have had a think about the points you raised and I have a few comments as follows:
I agree that in the ultimate case, ignoring the preload in the fastener is probably reasonable.
As regards the moments, I will think out loud for a minute...the bearing loads...
Hi all
I currently need to do a bolt bending calculation in order to choose an appropriate fastener.
The background is that I have a single shear joint between a 0.120" thick 7075-T6 rib foot and a 0.220" thick 7075-T7351 wing skin. Per drawing, the gap between the two items is 0.125", which...
I am an Australian aircraft structures engineer on the verge of moving to Canada for a year. I have read the above posts and the background information on Moltenmetal's link, and I am now quite worried about my employment prospects.
Can anyone give me some advice on the Canadian aerospace job...
