This is a question in response to R. Ay's discussion on trunnions!! Is there any consideration for stress intensification factors involving trunnions based on non-uniform geometry where nominal stress equations apply?? For instance in FE/Pipe, there is a template set up just for base ell/trunnion supports of which, in the output, calculates inplane and outplane SIF's for the trunnion and bend. FE/Pipe claims that these SIF's can be used in a beam-type analysis such as Caesar. Also, how do we account for the absence of flexibility in the elbow with a trunntion attached?? I know these are rookie questions but alot of people here in the office have been asking these same type of questions.
