Homework Help: Burst test calculation help

  1. Mar 14, 2012 #1
    Not really a homework question, but it could be. Working on making a burst test chamber and need some calculations that says it is safe enough. Sorry for my poor english, it's not my first language.

    1. The problem statement, all variables and given/known data

    The setup: First a brass fitting would be fitted inside a chamber, and then pressurize until burst. I would like to know how much stress the bursting object gives to the surface of the chamber.

    My current numbers:
    Fitting weight: 202grams.
    Pressure: 150bar (=15000kPa)
    Diameter inside the pressurehose: 15.23mm
    Length to nearest surface: 5cm
    Length to bottom of chamber: 15cm

    Do I/you need more numbers?

    How thick stainless steel plate will I need so the 202gram object pressurized at 150bar won't give dents?

    Thank you!

    2. Relevant equations


    3. The attempt at a solution

    Not sure....
