Longitudinal Stress

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

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


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

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

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

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