Not designing per any code.
Material is plastic in sizes from ~4" through 36" nominal diameter. OD reduction is from DI-OD to IPS-OD (25.8" vs. 24.0" OD for example).
The closest charts I have found are round shafts with shoulder fillets but 1)these charts are for solid rod and not tubular...
Hello, I am considering a pipe reducer machined from billet where the ID remains constant but the OD is reduced. I would like to calculate relative stress concentrations of different fillet/radii in this corner stemming from internal fluid pressure.
I am having a hard time finding the right...
I think OP needs to take a new assembly (to better simulate conditions) measure fasteners, torque to spec, and measure fasteners. Use the information to generate an expected range of elongation and apply this to the failed assemblies
I like this idea, thanks. There are 20 bolts on these, I...
I did that too, but there was significant corrosion to the nuts/bolts and so I don't trust the break-loose torque to be accurate--values were all over the place. I was planning to compare the measured break-loose torque to the torque calculated by bolt stretch/relaxation just as a point of...
We suspect inattention during assembly. Manufacturers installation instructions are given in terms of foot-pounds. This is a backwards way of trying to approximate the torque applied to check on whether the installers followed suggested procedure or not.
Doing some forensics work on an assembled mechanical joint. I took measurements of bolt length in the assembled state, and after disassembly. I'm attempting to calculate the torque load based on this change in bolt length. Any ideas how I could do this?
