Hi all experts,
Can I set up my simulation with sand material? What card image I need to use? How to set up parameters for sand? It's the first time I deal with this material so I got some problem ))
Thanks all.
Hi Nancy,
There are several ways to simulate this type of material in Radioss, but mainly all of them are based in Drucker-Prager work. The Material Laws that can be used are /MAT/LAW10, /MAT/LAW21 and /MAT/LAW102. More info about them and how to set them up are provided in the following links.
/MAT/LAW10 : https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law10_dprag1_starter_r.htm?zoom_highlight=/MAT/LAW10
/MAT/LAW21 : https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law21_dprag_starter_r.htm
/MAT/LAW102 : https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law102_dprag2_starter_r.htm
A first approach of Drucker-Prager work can be found in the following page.

The use of the above laws depend mainly on the amount and type of available data you have for your material.
