Your equation (P * r / t) is valid only for constant radius. Using local radius is not correct IMHO. To be certain about that just imagine there is a flat spot in the section (r=0). How does this formula work in this case?
"why click "NO" if solution non linear"
If you click “Yes” femap reads ONLY Nonlinear results.
If you click “No” femap reads All results (both Linear and Nonlinear)
WKTaylor, NAS9921 is shear type bolt? It says “SHEAR… SHORT THREAD”. Is it suitable for high tension load? Or in other words: what Ti bolt works well in tension?
Thank you guys for comprehensive comments.
“fatigue life of the mating parts”- It was checked. Results are Ok.
“Have they run this analysis with both materials and compared the results” – No.
“You say you are considering steel fasteners instead. What type?” - If it were for me, I would...
I don’t have absolutely strong arguments otherwise this post would not exist. Of course the first thing that anybody would look at is static and fatigue analysis. That’s why I mentioned them immediately in the first comment. I am looking for pros and cons beyond those two.
Here is my humble...
Thanks for your reply.
Just to be sure that I am clear enough and we are talking about the same thing. My question is only about the tension bolt in that fitting (see picture below).
Hi all,
In one fuselage design of a transport aircraft I saw titanium hi-loks DAN7 in classical channel tension fitting. Fitting connects two parts of a beam and the beam itself is a longitudinal sill over fuselage door cut-out. Primary structure. Usually (to my experience) steel fasteners are...
