Radial Pressure Stress, Inside (=RPS) - 09/29/03 03:12 AM

confused
I have been tring to figure out Von Mises Stress used in
Caesar. What is RPS, and how to calculate RPS?
It is indicated in T2-9.

Radial pressure stress in the simplest form has a magnitude zero on the outside and -P on the inside wall of the pipe.

"radial pressure stress, inside" = longitudinal pressure stress * ( 1 - Router^2 / Rinner^2 ), where

- Router is the outside pipe radius
- Rinner is the inside pipe radius

Note, the longitudinal pressure stress is computed using the equation:

stress = Rinner^2 * Pressure / (Router^2 - Rinner^2).
