Yade

Particles or macroscopic arrangement properties?

Asked by Daniel Enrique Morales Molina

When I define the E and poisson in a ElastMat, those refer to particles or arrangement properties?
Thanks.

Of course they refer to particle material properties. Whether they match
real physical quantities or not depends on the type of model you use. For
this same reason you may need to calibrate them.

Thanks Chiara,
Wasn't clear for me because in the "Estimation of \Delta t_{cr} by wave propagation speed" part of DEM background (https://www.yade-dem.org/sphinx/formulation.html), you can find "Note that in this section, symbols E and \rho refer exceptionally to Young’s modulus and density of particles, not of macroscopic arrangement." so someone can think that everywhere else E and \rho refer to macroscopic arrangement.

Thanks Chiara Modenese, that solved my question.
