How to obtain transverse shear from shell elements?

[Yi Yi Du]

Hello!

I am running an explicit simulation that applies torsion and internal pressure to a cylinder wall, which is modelled with shell elements (S4R). However, I am having trouble getting the transverse shear stress (TSHR, transverse shear stress for thick shells) when torsion is applied to the cylinder.

I've tried modifying the settings under sections in ABAQUS CAE: adding a thickness modulus, density, and transverse shear stiffnesses (K11, K12, K22). But I still can't get TSHR, transverse shear stress for thick shells, in my results.

Please advise, and thank you!
