Stress/strain in a pipe

  1. Oct 8, 2011 #1
    Two situations:

    * A pipe with high pressure fluid inside - stress determined by hoop stress.
    * A pipe with high pressure fluid outside

    Suppose the pressure differences are the same in each situation, which would have less stress?

    Or are they equal?

    My first thoughts are that if the pipe is being compressed by higher pressure outside, it is less likely to buckle than high pressure inside.

    ┬┐what means for you less stress?
    Are you speaking about less Von Misses Stress, Treska,....? principal stress??
