      Dear team,

      I want to simulate notebook drop in LS-DYNA and I use EPE foam to absorb impact force.

      I have studied papers on EPE foam simulation and it seems that mat57, mat63, and mat83 can be used.

      Which material card is better for EPE foam?

      Thanks!

      Hi @Water, mat57-- for low density foam ,mat63-- crushable foams (as in flower foams) ,mat83-- for low and high foams ( seat foams and cushion) , based on these, take the material model as described in "Article" and see if you can replicate the results first and then adapt other mat models.
      Cheers, Ram
