Hi everyone,

I want to use YADE to simulate the particles crushing of calcareous sand in a 
triaxial test, and recently I found a more suitable method to simulate particle 
breaking. It is  a discrete fragmentation method, a multigenerational approach, 
in which single element break and are replaced by a new generation of smaller 
grains(daughters). This method need several further modelling choices. The most 
important ones are a particle failure criterion and a particle spawning 
procedure. The particle failure criterion is used to decide when a particle is 
crushed, and the particle spawning procedure establishes the relationship 
between the disappearing broken particle and the new generation of smaller 
particles that replace it. So my questions are: How can I achieve the process 
of replacing large particle with smaller particles ? Any idea ? many thanks in 
advance!

Yang
