A viscous friction model

A viscous friction model is developed which represents the dynamic or transient behavior of viscous friction. Stated as a general rule of finite viscous friction, the viscous friction force lags the velocity that produces it and in steady state it is proportional to that velocity. An experiment is designed and performed which validates the analytical model. A new combined friction model is also presented which represents elastic-plastic or viscous behavior. This combined model exhibits the unifying characteristic of reducing to various historical solid and viscous friction models in addition to the proposed viscous friction model.
