Reply To: Honeycomb Shear modulus Calculation based on Analysis – ASTM 273

[Can Ozturk]

My sample is 1/4 – 5052 – .0015. ASTM 273 has two option for specimen and these are core with facesheet or without facesheet. This is the TDS document and on page 13 there is information about the test, that is, the sample was tested without a facesheet, so the sample is directly connected to the test plate.

I thought about what you said about adhesive, but does this difference affect the shear modulus by almost 100 MPa? Then can't it be modeled at all because of adhesive, hc? Because unless you use the orthotropic material properties in tds, it will give wrong results. Isn't the geometry that gives the honeycomb core its shear properties the main factor?
