Finding a Cross Sections Moment of Inertia Area

Good Morning,

 

I had initially posted a reply to a thread looking just to measure the MOI, I figured it would be better to start a thread of my own.

 

I'd like to use CREO to calculate the Area MOI of some non-uniform geometry. Prior to doing that I wanted to test the tool on a known Area MOI before applying it to the non-uniform geometry.

 

What I did was took an I-beam, calculated the Area MOI and then pulled the same beam into CREO and tried to use the analysis tool to confirm that it shows me the Area Moment of Inertia in the Inertia Tensor.  But the units for the Inertia tensor are for that of just plain MOI (lb/in^2) and not the Area Moment of Inertia (in^4) - how would I measure this using Creo for a cross section?

 

Thanks,

MW

Cross section mass properties analysis will calculate and report what you are requiring. See this link for instructions:

To Compute the Mass Properties for a Cross Section (ptc.com)

 

Open the report window and you will find area MOI values reported. You will find it looks like this in the report with the expected units.

This works, thank you.
