Homogenized Directional loss factor for laminated structure

  Hi all,
  
  I am trying to model the stacked laminated core of an E-motor for modal analysis. In the model for modal analysis I want to include the damping in the structure.
  
  As the E-motor stator is a periodic structure of laminated steel and insulation, I am modelling it as a solid body with homogenized orthotropic material. I am using Ansys Material Designer to calculate the homogenized orthotropic material properties.
  
  The problem I am having is how to calculate the homogenized direction dependent loss factor for the stator (structural damping). Can I use the Ansys Material Designer for this purpose? Is there any other method to get the homogenized directional loss factor.
