  1. Hi all, From the Reference Guide of /MAT/LAW70, it says this material model is a visco-elastic foam material. However, I cannot find the right parameter which time dependent. So how to understand the visco property of this material model? Roy
  2. Hi all, Where can I get the theory manual of material law 70? I can only find some information about law 70 in the reference guide. I want to know more message and example about using law 70. In the reference guide, the example is about law 77 , not law 70. Any one can provide more message about law 70 (theory manual or examples or papers)? Thank you Roy
  3. Hi all, Which material model should be used for a package foam when doing package dropping simulation? From the help manual, both /mat/law38 and /mat/law70 are visco-elastic Foam Tabulated material. What's the difference between this two models? Is there any example about package dropping simulation? Best Wishes Roy
