Tuesday 14 May 2013AG dynamics seminar: Stick-Slip Transition in a Model with Dry Friction

Wolfram Just - QMUL

Kay Building, St Johns Room 16:00-17:00

A consistent theoretical description of friction is certainly one of the most challenging topics nature has still in stock. While talk won't contribute to this fundamental issue, we rather analyse a simple phenomenological model. In particular, we will focus on the impact of stochastic forcing on dry friction and the associated stick-slip transition. Analytical solutions of the Fokker-Planck equation and of the corresponding eigenvalue problem will be presented, uncovering the dynamical phenomena in this piecewise smooth stochastic model.
This seminar will be delivered remotely via access grid.
