bajwa,
bends tend to ovalize to create flexibity which is determined using bend radius,pipe radius & thickness.
stress intensification factors were determined using fatigue analysis(7000 cycles normally)of inplane and outplane bending of pipes and finally they have derived an equation.
U can find these equations in B31.3 APPENDIX D.

arun,

No doubt you understand the issue but you did not quite get it right in your posting.

Anyway, this discussion moved to the end of this thread:

It is time to lock this thread and move along.
