Material Params for Wheat Straw and Roots

H_Engbert

Hello there,

i am looking for material parameters of crop stubble and its roots for the simulation of crop residues in a soil particle bed.
The stubble is to be modelled as a meta-particle with the help of bonds.
Accordingly, in addition to general material parameters such as density and coefficients of friction, I am primarily looking for values for the bonding settings.

Unfortunately, my research so far has been rather unsuccessful.

Many thanks in advance.

Regards,
HE

Hi Hendrik,

If you can't find the values ​​of the material parameters in the literature then you should calibrate them yourself. To learn more about calibration, you can check the following videos:
