  How to use aluminum foam properties in Ansys Autodyn. basically, I am doing an air blast simulation on the aluminum foam-based sandwich structure. but in the paper, the properties of the foam are not clearly mentioned, please go through the journal paper. for foam,what is EOS, strength model used?

  Hi, EOS is for equation of state. It's to model the behavior of explosive. More details in this paper for example: https://aip.scitation.org/doi/10.1063/12.0000827
  For Al foam, properties are given p344 on your paper:

  Yes, in the paper are given stress-strain curves and you could reuse these curves for the material model in Ls-Dyna, using *DEFINE_CURVE and then use this curve's LCSS ID in your material card.
  Here a tutorial on Youtube: https://www.youtube.com/watch?v=PxqRRSGh_yg
