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...

Although this diagram is for a lug with a rectangular cross section, it may help to understand the loading. When theta is at 90...

Just out of curiosity, using Roark's formulas 7th edition (Table 9.1, Case 6 - Solid circular or elliptical section), and the dimensions...

The comment was based on the fact that any +ve bending (tensile stress) seen at the smaller inner radius will effectively see a geometry...

Just mentioning it, but it may be considered in some other code(s), there's inter-bolt (or inter-rivet) buckling?

You may want to consider curved beam bending?
