How to test balsa wood

[Anonymous]

Is there a material add on for balsa wood complete with material properties so we can test?

You can always add on yourself...

Not sure if Inventor can provide accurate FEA results as it performs linear material analysis only..

Is this built into Inventor 2017?

I don't see it in my material list.

You can always add materials yourself.

Make it isotropic (even though wood is not) and use caution in the analysis.

Your instructor should be able to show you how to add a material.

If you can't figure it out - post back and I will find video instruction on the process.
