I am trying to model an impact problem on LS-DYNA where polyurethane is used as an adhesive between a ceramic tile and metal backing. I want to setup a BB model, but am unable to find the material properties to do so. Would you be knowing where to look for them? 

To setup my model, I'll be needing the following parameters: 

  • density
  • elastic bulk modulus
  • shear bulk modulus
  • viscoelastic shear modulus
  • elastic segment number
  • viscoelastic segment number
  • inelastic strain component
  • inelastic stress component
  • GAMO
  • Reference Kirchhoff Series


Any assistance would be much appreciated!!
