Global Bifurcations of Nonlinear Thermoelastic Microbeams Subject to Electrodynamic Actuationg escape from a potential well that is perturbed by both thermoelastic damping and modulated periodic actuation. This structure is investigated via Melnikov analysis to shed light on possible existence of global bifurcations and chaotic transients.

Nonlinear Interaction in MHD Bearings under Oscillating Electric Fieldscant and applying electric and magnetic fields, it is possible to produce pressure even if the shaft does not rotate and the bearing is fixed. The equations of motion for a rigid shaft supported in short MHD journal bearings are derived and solved numerically. By a similar analysis the slider bearing is examined.

0925-0042 olThe interest of the applied mechanics community in chaotic dynamics of engineering systems has exploded in the last fifteen years, although research activity on nonlinear dynamical problems in mechanics started well before the end of the Eighties. It developed first within the general context of t

On the Dynamics of a Railway Freight Wagon Wheelset with Dry Friction Dampingand hysteresis are included in our model of the dry friction..The resulting dynamics is nonperiodic and most likely chaotic. A bifurcation diagram and some interesting types of apparently chaotic motion are presented and discussed.

The Chaotic Oscillations of High-Speed Millingork investigates the nonlinear vibrations in case of period doubling and compares this to the well-known subcritical nature of the Hopf bifurcations in turning processes. Also, the appearance of chaotic oscillation ‘outside’ the unstable period-two oscillation is proved for low-immersion high-speed milling processes.
