Class FrictionPrms

object --+ | ??.instance --+ | InteractionPrms --+ | FrictionPrms

Parameters for rotational friction, a Coulomb frictional law with shear stiffness. Forces are applied at the contact point, which generates moments. Normal and shear stiffnesses are specified via a contact Young's Modulus and Poisson's Ratio

Parameters:

name (string) - Name assigned to this group of interactions.
youngsModulus (float) - elastic contact modulus used when calculating linear elastic normal force.
poissonsRatio (float) - contact Poisson's Ratio used when calculating linear elastic shear force.
dynamicMu (float) - friction coefficient when contact is sliding.
staticMu (float) - friction coefficient which governs the transition from static contact to dynamic frictional sliding.
rigid (bool) - When True (default is False), rigid body rotations of touching particle-pairs are taken into account.

Overrides: object.__init__
