Mani Bhuma

Hi Peter,

I originally attempted a solid body with orthotropic materials as you mentioned. Similarly, to the datasheet you provided I have the exact same datasheet of the material I am using. However, as you mentioned, the datasheet only provides three constants of the many. I tried to use an educated guess to estimate the other values, but I kept getting ridiculous mode shapes in the modal analysis. My solution to this issue was to recreate the composite with the honeycomb completely modelled, as I know the isotropic material the honeycomb itself is made of. Then, use the results of this new model to adjust the material values on the solid body until I got similar results. Please let me know if there is a simpler solution than this.


Thank you for catching that important feature I was missing in the honeycomb. Is there a way to model that into my simulation with surfaces?
