Note that honeycomb core is an orthotropic material, so you need three values for Young's modulus and three for Shear modulus, rather that just one Young's modulus for an isotropic material.  That also means you have to pay attention to which direction the honeycomb core is assembled into the sandwich so you put the right shear modulus in the right direction that matches the orientation of the geometry in your model.
