Hello

I am using LS_DYNA to do simulation work of crushable foam and need some properties of "Foam material (Sunstar Eng., High-stiffness urethane)" such as density and stress-strain curve.I need to calculate load vs displacement graphs for impact analysis, but the loads that I am getting out of the model seem to be incorrect.

Any help would be greatly appreciated!


Thank you very much!

Sincerely yours,

Jorgen

The mechanical properties of polyurethane foams are highly dependent on the specific material and density. Can you perform some experimental tests?
