Cracklike Dynamics at the Onset of Frictional Sliding [PDF]

, 2011
We propose an elasto-plastic inspired friction model which incorporates interfacial stiffness. Steady state sliding friction is characterized by a generic nonmonotonic behavior, including both velocity weakening and strengthening branches. In 1D and upon
