Hi,

 

I have some test data, which is used to model Abaqus Hyperfoam material. Now I am wondering how I can translate this measured to Radioss material model ?

    Hi Petri,

    You can use /MAT/LAW70 ( visco-elastic foam material) in RADIOSS which is equivalent to Hyyperfoam material in Abaqus. 

    I'm attaching a sample deck on Material Law 70. Please go through the same.
