Christian Jakob posted a new comment:
It is not double-checked, but quad-checked (maybe even more).
YADE input file:
#GENERAL SETTINGS:
initial_porosity = 0.4
shear_modulus = 3e7
poisson_ratio = 0.3
young_modulus = 2*shear_modulus*(1+poisson_ratio)
friction_coeff = 2
angle = math.atan(friction_coeff)
rho_p = 2650 #density of particles
#SET DAMPING CONSTANTS:
local_damping = 0.01
viscous_normal = 0.021
viscous_shear = 0.8*viscous_normal
PFC input file:
;GENERAL SETTINGS:
initial_porosity = 0.4
shear_modulus = 3e7
poisson_ratio = 0.3
friction_coeff = 2
rho_p = 2650 ;density of particles
;SET DAMPING CONSTANTS:
local_damping = 0.01
viscous_normal = 0.021
viscous_shear = 0.8*viscous_normal
The only thing I could imagine, that is wrong, is
young_modulus = 2*shear_modulus*(1+poisson_ratio)
but wikipedia tells me this is ok...
