Pipeline Section Modulus Modules

Calculate pipeline EI and section modulus.

The section modulus is equal to the moment of inertia divided by the length from the centroid to the outer fibre (the outside radius).

`Zs = I / Y `

where :

Zs = Section Modulus
I = Moment Of Inertia Or Second Area Moment
Y = Length To Outer Fiber

The section modulus can be used to calculate the maximum bending stress from the bending moment

`SB = (BM) / (Zs) `

where :

SB = Bending Stress
BM = Bending Moment

For a pipe the the outer fiber length Y = the pipe radius. For combined stress calculations, the pipe mid wall radius can be used as the outer fiber length. This is based on the non linear stress distribution through the pipe wall. A mid wall approximation from DNVGL is also included.
