Friction and Damping
Hello!
I would like to ask about my doubts concerning friction and damping.
sim.createInter
FrictionPrms(
name="friction",
youngsModulus=
poissonsRatio=0.25,
dynamicMu=0.4,
staticMu=0.6
)
)
sim.createInter
LinDampingPrms(
name="damping1",
viscosity=0.002,
maxIterations=50
)
)
sim.createInter
RotDampingPrms(
name="damping2",
viscosity=0.002,
maxIterations=50
)
)
According to the tutotial: "for elastodynamic problems, a small value is sufficient (viscosity < 0:05) whereas for quasi-static problems a value as large as viscosity ~ 0:5 might be appropriate." and "the staticMu coefficient of friction is applied when two particles are in static frictional contact, i.e., prior to the fi
rst time the frictional sliding criterion is met. Thereafter the dynamicMu coefficient of friction is applied. By setting dynamicMu < staticMu, one can simulate the physical observation that the frictional force required to maintain sliding is less than the force necessary to initiate sliding."
However, do these parameters (viscosity, dynamicMu, staticMu) depend on any parameters of the model?
Thank you and best regards!
