… in a closed thin-walled non-circular cross-section#

For closed thin-walled non-circular cross-sections the shear stress is defined by:

\[\tau = \frac{M_t}{2A_mt}, \quad I_t=\frac{4A_m^2}{\oint\frac{1}{t}dm}\]

This is treated in chapter 6.3.1 of the book Engineering Mechanics Volume 2 (Hartsuijker and Welleman, 2007).
