Thank you for the detailed response. I have a lot more clarity now!
Is there a reason you chose a very specific deformation scale factor of 7.9288e-3?
I reran my simulation to adjust the deformation scale and take a closer look at the results, but I found my results were quite different from yours. Did you change any of the material properties? I noticed you also used a couple 'Sweep Method' features in your mesh. Does this just increase the speed of the mesh, or does this significantly change the formation of the mesh? I attached images of my results below.
As you can see from the images, it seems the face sheets are not experiencing any deformation and the bending modes' frequencies are quite different from your results.
How would I use the results from a 3 point bending test to estimate good material constants in modal analysis?
