Hello again Peter,

So I did everything that you suggested and finally the simulation did present quite acceptable solutions.

I want to ask though. What are the differences of Equivalent stress (Von-Mises) and Normal Stress ? They have different values for the core that I am mostly interested in since its a solid block but with Orthotropic properties (AL 5056). Also, when I press play those values change.

Equivalent Stress: 

Normal Stress: 

Should I add any other solution specifically for the purposes of looking if the honeycomb works as intended ? I just want to show that this method works and that its not necessary to model an actual 3d solid honeycomb. 

Thank you for your time.
