In the test I refer to, which was a large fabricated panel with several stiffeners under compression, whole joints unzipped. There was an equal mix of pull-through and shank failure. It was not really possible to identify precisely where it began - i.e. whether the initial failure was...
Thanks. I have this manual and have just looked it up.
There is a wide variation in what should be used for allowable slug rivet tension. For 1/4" csk, NASA quotes up to 2265 lbf. I have some in-house test results that are up to 2648 lbf.
However, we have a design value for tension that is 10%...
Anyone know where I can find tensile strengths of NAS1321 slugs in various panel thicknesses? This is not a primary loading condition but a seconday loading design requirement from wrinkling.
