Anybody knows the equation for finding out "Torsinal Rigidity Modulus" for pipes.
I am craeting a personnel library for pipes. In the Family Table editor there is a column named Torsional Rigidity Modulus. I am trying to give an expression for this but i dont know the equation for the same.
Hopes Somebody can help me for this equation .....

Thanks Blair...
I got another one also, hopes thats much helpful : https://engineering.purdue.edu/~ahvarma/CE%20579/References/AISC_Torsion_Guide.pdf
This may be of benefit as it seems Inventor desires the K of the equation

Which also corresponds to the Polar Moment of Inertia in the above listed links.
I was also looking for this as we made some pipes for our content center which needed the Torsional Rigidity Modulus.
In our case the Torsional Rigidity Modulus formula is exactly the same as the Polar Moment of Inertia formula.
This formula can be verified by creating a pipe cross section sketch in a part file, RMB and select 'Region Properties'.
We used Excel to do all the calculations, easy once you have the correct formulas.
Thanks to the above posters for pointing out the right direction.
