Longitudinal Stress

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

tension stresscompression stressThe stress imposed on the long axis of any shape.  It can be either a compressive or tensile stress.

For a pipe the stress is usally produced by the fluid pressure in the pipe and then acts upon the pipe wall.

Longitudinal Stress formula

\(\large{ \sigma_l  = \frac{ p\;d }{ 4\;t }  }\)

Where:

\(\large{ \sigma_l }\)  (Greek symbol sigma) = longitudinal stress

\(\large{ p }\) = internal pressure

\(\large{ d }\) = mean pipe diameter

\(\large{ t }\) = pipe thickness

Solve for:

\(\large{ d  = OD - t  }\)

\(\large{ d  = ID + t  }\)
