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
