You could start with /MAT/LAW70 for foam material, using /PROP/TYPE14.

thanks, for the answer, I just tried with law 70 but i think the data given from the reference guide aren't for the EPS (crushable polystyrene). I need this data for the analisys of a tv falling down with his box. I need also the value of the parameters of material's card of the "bumpers".

If you have this data you could help meeeee

Unfortunately I do not have any reference data that I can share with you.

Maybe you can find some reference, based on the material density, from technical articles.
