I am trying to analyse the macroscopic model of Aluminium Honeycomb in Ansys Workbench. For the analysis, it is necessary to have the strength values (Yield,Tensile and Compressive) of the honeycomb. I read a few papers but was unable to find something useful related to the strength values of Honeycomb.
kindly check following papers hope will be useful

You can use the strength values for the aluminum in bulk state. then you can did a tension test using ANSYS workbench using the honeycomb geometry. the lower part of the model is fixed and upper part will be under tension with tabulated displacement. You get from the result a relation between displacement and the reaction force of the fixed side. this relation you can convert it to stress strain relation. from this relation you can extract E and Sy. On the same similarly, you can make the compression test.
I think you can find some studies about mechanical properties of aluminium honeycomb. You can model the part as a bulk (solid elements) volume and apply the macro-properties coming from experimental data.
If you need to simulate the micro.behaviour of the part, you can use a RVE approach.
Let's take a look to RVE methods (there are two publication in my portfolio).
I can calculate the orthotropic elasticity parameters like,E,G and poisson's ratio for different directions but I need to calculate the limit stresses for failure in different directions(as listed under Strength->Orthotropic Stress Parameters) for the FEA failure analysis of the Al-Honeycomb.
