                 RotFrictionPrms

Parameters for rotational friction, a Coulomb frictional law with shear stiffness. Forces are applied at the contact point, which generates moments.

(Constructor)

 

Parameters defining frictional interactions between rotational particles.

Parameters:
  • name (string) - Name assigned to this group of interactions.
  • normalK (float) - elastic contact modulus if scaling is True (default) or spring constant if scaling is False, used when calculating linear elastic normal force.
  • dynamicMu (float) - friction coefficient when contact is sliding.
  • staticMu (float) - friction coefficient which governs the transition from static contact to dynamic frictional sliding.
  • shearK (float) - elastic contact modulus if scaling is True (default) or spring constant if scaling is False, used when calculating linear elastic shear force.
  • scaling (bool) - When True (default), elastic stiffnesses are scaled according to particle dimensions.
  • rigid (bool) - When True (default is False), rigid body rotations of touching particle-pairs are taken into account.
  • meanR_scaling (bool) - use mean particle radius instead of min particle radius as the radius of bonds
