Longitudinal Stress

on . Posted in Classical Mechanics

longitudinal stress cube 2longitudinal stress cube 2The 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

\(\large{ \sigma_l  = \frac{ p\;d }{ 4\;t }  }\) 
Symbol English Metric
\(\large{ \sigma_l }\)  (Greek symbol sigma) = longitudinal stress \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ p }\) = internal pressure \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ d }\) = mean pipe diameter \(\large{ in }\) \(\large{ mm }\)
\(\large{ t }\) = pipe thickness \(\large{ in }\) \(\large{ mm }\)
