How do I extract the second moment of area being calculated by an I profile

[pc2021]

I want to confirm that the second moment of Areas being calculated by Abaqus for a I profile matches my calculation. I am aware query allows us to see the moment of inertia about the center of mass but that value does not match, because I am assuming it is in regards to the mass of the element and not the area. any direction is helpful

 

[FEA way]

To calculate section properties in Abaqus you can do this:
- create a 2D part and draw your section, then mesh this part with plane stress/strain elements
- assign material to the part
- add the part to assembly and create some analysis step (for example general static)
- write the input file and edit it:
* replace the type of elements with WARP2D3 (triangular) or WARP2D4 (quadrilateral)
* replace the step with *Beam section generate

Run this analysis and you will get a .bsp file with section properties for your geometry.

You can find more details about this procedure in the documentation chapter "Meshed beam cross-sections".
