  Hello, i searched for a solution to create materialdata for a cylindrical Honeycomb-body. I found some topics about this for plain structrures
  I am currently working on validating the results obtained from manufacturing of honeycomb sandwich structure with its honeycomb core made of Kevlar, using FEM. While the defining of Isotropic material properties requires the input of combination of any 2 characteristic properties of the material, say, Poisson ratio and Young Modulus or Shear Modulus or Young Modulus, what has been received from the manufacturer's end is a data sheet which lists its Compressive Strength, Shear Strength and Shear Modulus (Requisite file attached), which does not seem to be sufficient enough for defining the material in ANSYS. Is there anything I am missing out or it can be done with the given data ? How to go about it ? (Note- The material code is PK2-1/8-3.0, the nomenclature can be understood by the attached file links)https://www.plascore.com/download/datasheets/honeycomb_data_sheets/Plascore_PK2.pdf https://www.plascore.com/download/datasheets/honeycomb_data_sheets/Plascore_Terminology.pdf

  Hi,nIn defining material, use x axis as radial axis, y axis as angular axis and z axis as longitudinal axis.nThen, in Mechancial, each element has a coordinate system to evaluate the material model. If the material is in terms of a cylindrical coordinate system then we can change the elements (part) to have the same coordinate system and not worry about a transformation. So first define the coordinate system. Then change the part(s) properties to use that coordinate system:And as a good check you can use this result to plot the coordinate system triad for each element.nnApriln

  Have you tried using thr Material Designer, it is one of the best way to model the Microstructural properties. Just make an unit model of the cylindrical HC model and use the Material Designer to evaluate the E(XX,YY,ZZ) and G(XX,YY,ZZ) this can work if you are in static regime,n
