a few yrs back (!) I started this thread on trying to find a K value for SS screws into aluminum.

The above thread is closed so I figure I'd start another.
I tried to get the company to do a load cell study to measure clamping force vs...
this is a new problem that started once I removed adobe reader. I had both adobe acrobat 8 and reader 7 on this machine and removed reader. Before I could insert a pdf into mathcad with no problems using: insert, object, create from file, browse.... Now when I insert a pdf, the image doesn't...
hi, I have a cylindrical assy whose geometry repeats every 120* and would like to do the analysis on a 120* section instead of the entire assy. I have used symmetry on a 90* section which is easy, but I haven't used another interval like 120*. I know this is a very common analysis method but I...
when doing an FEA that includes clamping forces for fasteners in a bolted joint, what is the allowable stress for the area under the bolt head that's subject to the clamping force? When you have a joint with large diameter fasteners, and allow for a ~20000 lbf clamp load you can see higher...
here's a general question that would apply to any FEA program.
I've recently done some FEAs on round flat plates, fairly easy analyses, relatively low stresses, basic stuff. Lets say a 15-18" dia .5" thick plate using a .12 mesh size. Just making up numbers, I'll get a max stress of 6000 psi...
a very basic question on weld calcs and I'm surprised I'm asking this, but...
I'm looking at Shigley and Mischke ME Design, 5th edition. Welded joint section, pg 399-401, the bracket for mooring small watercraft example. It's a classic example of calculating weld stress and then stress in the...
I have found almost no info on this. I'm looking for a K value for a 18-8 SST bolt threaded into bare aluminum. Anyone have info on this? With all the aluminum used in automotive today someone must have done a lot of research on this.
please don't say "determine it experimentally" :) I know...
Any ideas on this one? Computer issue?
The model is a simple frame of square tubing, midplane meshed. The frame is ~30x30x96, so it's somewhat large, and I'm using a .25 mesh with six r6" refined areas with .10 mesh there. It takes 20-30 minutes to run the analysis so it doesn't seem like I'm...
