Custom Breakage Model with MultiSphere Particles

Clemenslischka

Hi,

i want to implement a custom breakage model that works with MultiSpheres and preferably with GPU as well. It would simply accumulate the principal stresses over time on a MultiSphere particle and after a critical value is reached would randomly select and destash a primary particle in the MultiSphere to simulate breakage.

Is this possible? I would be very glad if someone can point me in the right direction if this is doable in EDEM.

Thanks!

Hi Clemens,

Though you asked for how to implement a custom breakage model I wanted to be sure you were aware of the built-in Tavares Breakage model.  Is there a limitation with this model that is unacceptable for your application?

If there is a limitation I can provided you with some suggestions on how to implement your own damage model.

Kind Regards,

Eric
