linear or non linear stress analysis
linear or non linear stress analysis
(OP)
Which type of piping stress analysis to choose ? : linear or non linear ?
I nderstand that the nonlinear ( for suports and for friction ) simulates the real case more acuratelly
please your comments

For example, if you have a guide with a 1/2" gap, you have a non-linear boundary condition (the gap).

Ihave the AUTOPIPE, and it has the option of doing it linear or non linear.But my question is which is more acurate

The issue is have you accounted for them in your model???

According the AUTOPIPE manual, the non linear is more accurate.
So , any coment?

If you have a non linear system it should be modeled with its non-linearities (ignoring gaps 1/16" or less of course). It should also be run with and without mu to bracket the answers.
All this of course is appropriate for critical systems as opposed to service piping.
