Abstract :
The presliding displacement and stiction properties of friction models are investigated. It is found that existing single-state-variable friction models possess either stiction or presliding displacement. Next, those models with continuous states are interpreted as examples of Prandlt´s elasto-plastic material model. A class of general one-state models is derived that is stable, dissipative and exhibits both stiction and presliding displacement
