Ok, let's ignore even talking about a boot since y'all seem to be hung up on that part. If I have a weld in a straight line "X" inches long, and I apply a load "Y" parallel to the weld axis, so the weld experiences shear, then I remove the load, and then I reapply the load in the opposite...
FEA is what I was directed to do, and I don't have any pictures of the cracked weld to look at anyway.
The ultimate goal is to alter the design of the boot in a way that increases the lifetime of the boot, hopefully to the point that the weld never cracks. The point of the FEA was to compare...
I have a shaft connected to a piece of equipment, with a protective covering welded between the piece of equipment and the shaft to protect the hardware the shaft is attached to the piece of equipment with from corrosion. As the equipment rotates, the shaft bends, pulling on the boot and...
Yes it is, perhaps I wasn't clear. I am trying to look at the potential for stripping the threads due to fatigue of the weaker 304L threads from the combined axial load on the screw, not the screw itself shearing.
Hello, I'm looking for resources on how to determine fatigue life of the threads in a joint under cyclical loading. I have a grade 8 1 1/4-7 cap screw clamping two pieces of 304L, with the second piece of 304L being tapped to hold the cap screw. The cap screw has a preload of about 24% of its...
