    Piping FEA with thermal expansion gives bad results

    Steven Rickert

      I am trying to simulate a simple piping system in solidworks. I have a reference from an old book which I am using as a base line. The pipe is fixed at both ends with an internal pressure and thermal expansion applied.
      My book tells me I should get a bending stress of 8714 psi. The FEA reports a max stress of over 184000 psi.

      Obviously I am doing something wrong here. Can someone please give me some guidance?
