Explanation of MLAW 10 - Drucker Prager Material Law in Tandem with SPH

Crashphys

Hi all,

 

I am looking to model a granular material in Altair RADIOSS. I am using SPH with MLAW10, the Drucker Prager failure criterion, however I am not entirely sure it makes sense to do it this way. Does using MLAW10 assume that the SPH mesh will be one large chunk of coal, or individual pieces of coal with the Drucker Prager failure criterion?

 

Thanks in advance.

Hi,

 

check the Solid to SPH Option (Sol2SPH) in the attachment (from Radioss User Guide).
