                 NRotFrictionPrms

Parameters for non-rotational friction, a Coulomb frictional law with shear-stiffness. Forces are applied at particle centres, not at the contact point.

Method Details [hide private]

__init__(...)
(Constructor)

 

Define parameters for linear elastic frictional contact interactions.

Parameters:
  • name (string) - Name assigned to this group of interactions.
  • normalK (float) - spring constant used when calculating linear elastic normal force.
  • dynamicMu (float) - friction coefficient when contact is sliding.
  • shearK (float) - spring constant used when calculating linear elastic shear force.
  • scaling (bool) - When True (default), normal stiffness is scaled with particle size.
Overrides: object.__init__

getName(...)

 
Returns: string
Name assigned to this group of interactions.
