  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?

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

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