Slope stability in Yade

Asked by Mario Reyes

Hello,

I am a begginer using Yade and I am trying to start a small project related to slope stability. The objective is to learn Yade and maybe to do something more elaborated in the future. I am deciding the extension of my project and I have been reading the Yade manual and Catalano (2008) thesis (https://yade-dem.org/w/images/a/af/SlopeStability.pdf). I have some idea in the creation of the bodies, but I am struggling in how to implement the engines for the force-displacement and motion laws. Any guidance or reference will be of great help. If there is any other reference in how to perform a simple slope stability analysis using Yade (i.e. calculate a factor of safety) it would be excellent. Sorry if this is not the appropiate forum to ask these questions.

Thanks in advance.

Hi Mario,

For all questions related to Yade, I guess there is no more appropriate forum, so welcome !

- About "the engines for the force-displacement and motion laws", there is nothing to "implement", you may enjoy what exists already. It should be explained here:
https://yade-dem.org/doc/user.html#base-engines
There is one "NewtonIntegrator" engine that takes care of motion laws, see [1].
For force-displacement laws, all operations takes place in this "InteractionLoop", it has be defined carefully, see [2] and examples to understand how it works.

- Regarding slope stability analysis, DEM analysis (as performed with Yade) do not have many things in common with limit equilibrium analysis.. The questions (hence, the answers) addressed by these two methods are rather different..
