Knowing the loading, I would construct a FBD for each load case. This will enable you to determine the load paths. For instance, it...

Thanks for your interesting info Blas. The world of FEA seems to give you many ways to model lug joints!

Just as an indication, these are the current hand calc to FEA results (use of older FEA results). The shear is seen to be more...

The k I’m referring to is the pressure overclosure slope factor (compression spring stiffness) used in FE contact analysis. I’m looking...

The purpose of my investigation is to try and predict the Pmax and to obtain the kt. I’m not trying to predict any failure mode, to do...

The FE model is 1/4 of the lug, so you're seeing 1/2 the lug thickness. This is the most current FE model version (done today with a...

For the 0.75 dW lug, this is the contact bearing pressure I obtained. As you can see, it's relatively constant and locally peaks...

Thanks for your feedback. Just some background info. Out of pure interest only, the task I set myself was to see if I could devise a...

Hi to all you FEA guys! Hoping you can shine some defining light onto an FEA aspect where I need to gain some more clarity. The subject...

If you want to do a hand calc, there's a few ways you can do it. For the cylindrical section in the middle, I would look at using...

For a buckling analysis, I’ve seen the MS based on compression and bending allowables (P/Pcrt + M/Mu = 1) where Mu is the moment...

Just pointing out, for fatigue loading I would think the kt factor will apply to the threaded region only, where the bending should be...
