Torsional Constant of Cross Section
Torsional Constant of Cross Section
(OP)
I am attempting to calculate the torsional constant (area polar moment of inertia and warping constant) for an irregular cross section. I have the cross section image in DXF format. I read about Matlab programming that can calculate the polar moment of inertia by thresholding the picture and integrating the pixels. I can also construct a CAD file and I have access to Autodesk Inventor although I think at best this will provide the polar moment of inertia. I tried downloading the demo version of ShapeDesigner which does provide the actual torsional constant and warping function but the demo version doesn't allow any functionality. Any tips/thoughts on software or other routes that I might be able to use would be greatly appreciated.
Thanks!!!!
Thanks!!!!





RE: Torsional Constant of Cross Section
I have the same problem as you computing J and CW. I contact support at mechatools.com for the ShapeDesigner Software. I send them the dxf file. The Demo version of shapedeigner is limetd to 12 points and 2 shapes and the DXF conversion not allowed in the demo version.
I purshased the ShapeDesigner V6.4 and really it works reslly good, So I resolved my problem
I hope this helps you
