    Non uniform wall thickness.

    When calculating the approximate hydrostatic burst pressure of a part that has a non uniform wall thickness what is the proper way to go about doing the calculation? Can I just take the wall thickness at the thinnest section and apply the formulas for thin walled pressure vessels, or is this...

    Reaction force on shear coupling.

    I would like to compare my hand calculations to a FEA simulation. Here is the original question I posted regarding calculating the force generated by the coupling to shear some set screws: https://www.eng-tips.com/viewthread.cfm?qid=441875 In the image below, I have applied an internal...

    Pressure required to shear screws.

    I am trying to calculate the amount of force that is applied to a fitting, when an internal pressure is applied to it. The red line shows the area where the pressure is applied, the blue dot is the shear screws, and the yellow arrow is the direction the fitting moves when the screw shears. The...

    What is the proper way to apply GD&T to a box thread with an internal sealing surface?

    I apologize if this is a repeat thread but I could not find the answer I was looking for. In the file I attached is there a proper method to apply a geometric dimension based on the Face Square To Thread note. I would like the shoulder to be perpendicular to the thread so that when the...
