Linear Tangential contact forces in MercuryDPM implemented as FrictionSpecies, FrictionInteraction and SlidingFrictionSpecies, SlidingFrictionInteraction.

Force Computation:

void FrictionInteraction::computeFrictionForce()

FrictionInteraction::computeFrictionForce

void computeFrictionForce()

Computes the forces arising due to all three types of friction, i.e., sliding, rolling and torsional.

Definition: FrictionInteraction.cc:108

void SlidingFrictionInteraction::computeFrictionForce()

SlidingFrictionInteraction::computeFrictionForce

void computeFrictionForce()

Computes the tangential force generated due to compression in the sliding spring. Does take into acco...

Definition: SlidingFrictionInteraction.cc:106

The model parameters (e.g. sliding stiffness, rolling stiffness, tangential coefficient of restitution, etc) are set using FrictionSpecies (and SlidingFrictionSpecies) member functions
