Nonlinear dynamics can be a means to improve the properties of energy harvesting devices. Mathematical analysis of these systems as a tool for design or interpretation of experiments requires the solution of nonlinear differential equations. Most works use the third-order polynomial force (Duffing model) in order to qualitatively model mechanically nonlinear features. However, under large vibrations,...
It has been shown that the complicated nonlinear vibration phenomena in mechanical workpieces under excitations of intense ultrasonic pulses increase greatly the detectability of defects (cracks). To study the nonlinear vibration phenomena of plates induced by the ultrasonic pulses, an electrical circuit model is proposed to simulate the mechanical vibro-impact motions between the transducer horn...
