Homework Help: Stress Analysis - compound cylinders

  1. May 6, 2010 #1
    1. The problem statement, all variables and given/known data
    problem attached

    2. Relevant equations
    but lame equations i think they are?

    3. The attempt at a solution

    this is an assignment question that i have wasted countless hours on trying to solve without success. The problem is WBVMMECH025 from the anasys 12 verification manual (problem is attached) i have completed the anysys analysis with correct results and now have to do hand calculations, im sure that the interface pressure is correct, im sure i am using the right formula to find tangential stresses due to interface pressure and that those answers are correct. I think it is after this where i try to find the tangetial stresses due to the applied internal pressure is where i am going wrong but cant figure out why. have attached a clean copy of my attempt and the excel formulas should be correct cause they match my hand calculations.

    all help greatly appreciated

    edit: files were too big for attachment so i hosted them externally
