@3DDave That's definitely a fair point with regards to pressure vessels, something us in the amateur rocketry community have enormous respect for. We test our motors at a professional facility in the Mojave with members present in a steel reinforced blockhouse. I am of course, looking for a...
@SnTMan We can definitely go with shear at that minimum edge distance as an appropriate approximation for the worst case scenario. I have always designed this using rule of thumbs etc. would be nice to be able to optimize. Any literature you know of on the topic? Really appreciate the input...
@SnTMan Mike, thanks for the response. My fault, should have uploaded higher quality. To confirm, you're referring to double shear of the two planes shown in this image?

@3DDave This configuration is for a solid rocket motor propellant characterization test; the "pressure vessel" is really the combustion chambers which operates at 1500 psi. Obviously, there are seals and a nozzle on one end; didn't think it was necessary to go into detail about the whole...
Not sure if that upload will go through properly ^
The bolts are working entirely in shear arranged radially about the tube. Would like a nice way to calculate the amount of tube material needed to keep the bolts retained. They should be placed as close as possible to the end of the tube...
I am building a pressure vessel made of a round tube with two disk closures; the closures are retained by 1/4" bolts. I would like to minimize the distance necessary to install the retention bolts from the end of the tube. Would you calculate this distance with simple average double shear, or...
