Torsion on materials of variable cross section

Click For Summary
SUMMARY

The discussion centers on calculating the torsion constant for solid plates with variable cross sections, particularly when holes are present. The user seeks methods to address this without resorting to Finite Element Analysis (FEA) or SolidWorks simulation tools. A suggestion includes integrating along the length of the plate, although this approach does not fully account for the changing shape. The conversation highlights the complexity of torsion in non-uniform materials and the need for precise calculations.

New here, sorry if I'm in the wrong place or unclear, etc.

I've been looking at torsion on solid plates and the torsion constant. I was wondering how to handle the torsion constant on a plate of changing cross section (e.g. there are holes drilled in it, changing the area of the cross section and shape, leaving it without a uniform solidity) without doing an FEA (I might have access to something like solidworks simulation stuff in the future, but not at the moment).

Originally, I thought maybe too integrate along the length for the changing area, but that doesn't account for the shape.

Can anyone help me? Sorry if this is a dumb question.
