Hello,
We have been using Sigma-X section in our office since 2007. It really does everything you would like to get regarding to section properties. The software will determine the properties of any section such as:
-Area
-Inertia
-Elastic Neutral Axis
-Plastic Neutral Axis
-Elastic Modulus
-Plastic Modulus
-Section Centroid
-Torsion Constant
-Warping Constant
-Shear Area
-Shear Centre
-Principal Properties and Equivalent Material Properties of any shaped cross section
You can calculate section properties using both the Boundary Element Method and the Finite Element Method. Section maybe drawn using buidl-in graphical interface (similar to drafting software), or can be imported from AutoCAD (DXF format) or digitised from scanned images. So as you can see for the little price (70$ if I remember right) you can get very powerful piece of software. You could think that for 70$ you will get another piece of junk but beliewe me..it is 100% accurate, very effective time saving "tool".
So again if you are looking for a software which will calculate torsion, warping constant and shear properties I think that the Sigma-X Section is the right choice.
Regards
