For this, I simulated the ASTM 273 test and tried to obtain the core shear modulus included in Hexcel&#8217;s TDS, this tds includes the dimensions of the test sample and the strain rate speed. I drew the walls of the honeycomb geometry as a midplane by taking into account the cell size, foil thickness, t 2t etc. and additionally defined bonded contact in the places where the walls touch each other (becomes 2t). Btw my mesh quality is almost perfect. It is written in the technical data sheet that the material is 5052 aluminum, I took these properties from MMPDS. Despite all this, the modulus I calculated as a result of my analysis is 239 MPa, while this value is 344 MPa in TDS. Why is this difference?&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;Even if I reflect the geometry exactly and include the fact that the material is isotropic 5052 aluminum and simulate ASTM 273 with the same sample size, I get a very different value than the shear modulus found in TDS.
