How to find Poisson Ratio of Honeycomb like Structure?


      Hello everyone,I am BE Mechanical Student, currently working on calculating poisson ratio of honeycomb like structure,for which I have fixed one part & subjected the other part to tensile load of 2000N.

      I am simulating this using static structural module of Ansys Workbench.

      I have calculated directional deformation in perpendicular/shear & axial direction.

      Is this the correct method to calculate Poisson ratio by dividing shear displacement/normal displacement for any type of structure including auxetic structure?

      (Link for FEA:

      Note:Load of 2000N has been applied along Y-direction.

      (Please refer the below images to see the Loading condition &results)

      Poisson's ratio is a needed material property and I think you will need experimental testing to determine Poisson's ratio.
