landslide simulation

Asked by dennis

Hi to all..

I'm just wondering if there are papers published on landslide or slope failure simulation
using esys-particle. Related papers will also help a lot. Although, there is an example in the tutorial,
I also want to know the parameters in the experiments which can be used for the simulation.

Sincerely,
dennis

Hi Dennis,

I'm not aware of anyone who has written papers on ESyS-Particle landslide simulations. The examples in the Tutorial are strictly for instructional purposes only. No attempt has been made to calibrate these model parameters versus laboratory experiments.

I suspect calibration will largely be similar to that for hopper flow simulations though. One will need to tune the model parameters to achieve a desired macroscopic friction coefficient (or angle of repose, if you prefer). The usual problems with using individual spheres will emerge: macroscopic friction of unbonded spheres is always significantly lower than real granular materials. This can be overcome by representing individual grains as clusters/aggregates of bonded spheres.

Cheers,

Dion.
