Damage models in Yade

Asked by Shubham Agarwal on 2020-10-30

Hello
From the Yade documentation, I could get that for bond-failure, strength based failure model is one. Are there other failre models too such as Cohesive zone failure model?

Thanks

Hi,

Just a comment, also inspired by your other question [1]: in DEM/YADE Discrete Elements are very often pretty much rigid (modulo the finite contact stiffness, which just correspond to linear springs in most cases), so I abandon any enhanced continuum mechanics model if I were you.

Unless you're already very familiar with DEM/YADE and would like to implement new stuff to account for complex deformation phenomena at the particle level..

Maybe you could describe more in detail / add some links what you exactly mean by "bond-failure", "strength based failure model" or "Cohesive zone failure model"?
thanks
