Law51 is a multi-material law. It means that a cell has the possibility at any time to contain some amout of each sub-material. So Radioss needs to have the information of each sub-material possible.

Law51 has recently been updated with a new formulation Iform=12 which is much more userfriendly. I strongly recommand you to use it.

I attach you a 2D axisymmetrical cylinder test model with LAW51 - Iform=12 formulation. I hope it will be helpful or you.

Hi Mathis,

Your answer exactly solved my difficulty.

Thanks very much!

By the way, could you mind to explain to me the purpose of Polynomial and JWL equation of state in Radioss?

Thanks!

Hi Mathis,

Why we have to enter double parameter for copper here.

Hi James,

Please look at the slide up. I hope it answer to your question.

Hi James,

It is not really necessary. It is just that as law51 has up to 4 sub-material, I like to put all of them just in case. Again, purely optional
