Are polyhedra aggregates of spheres?
Good evening,
I am considering using Yade for a project for which I need to simulate large pieces of ice breaking under certain forces. The idea is to start with a large polyhedron shape which breaks into smaller polyhedra under compression forces. This has been done with Yade before https:/
So my questions are:
- how does the algorithm decide in which point the material breaks and how the crack propagates in 3D?
- What is the internal structure of the polygon? Is it made of spheres (in this case the sigma-forces would be given by the sphere-sphere contact forces)?
Thank you and best regards,
Damiana Catanoso
