Cover Story: Mechanical systems in which two parts slide over each other with friction are usually designed to work in a smooth and flawless manner. Nevertheless, jerking motions promoted by stick–slip phenomena may develop and yield a complex dynamic behavior even for systems in which only a few degrees of freedom are involved. Stick–slip motions are observed in a variety of mechanical systems. In the present work, the paradigmatic case of an elastically restrained rigid block in contact with friction to a rigid support is considered. Despite the apparent simplicity of this system, the analytical study of its dynamics and limit cycles is not trivial and can shed some light on important features of the nonlinear dynamics of more complex physical systems. View this paper
