...Wenguo Zhu; Marco Morandini In this paper, the nonlinear modeling of beam energy harvester embedded with piezoelectric transducers is presented. Starting from a multibody dynamics perspective, a fully coupled electromechanical nonlinear beam model was derived and a geometrically exact finite volume...

...G. Kolappan Geetha; D. Roy Mahapatra; Chi-Won In; D. A. Raulerson Transient vibro-thermography for nondestructive evaluation and super-resolution imaging of material defects invariably employs nonlinear contact dynamics involving the ultrasonic actuator (horn) and the surface of the target...

.... Editor: Prof. Philippe Velex. 10 06 2013 13 02 2014 Torsional systems with clearance-type nonlinearities have inherent vibratory problems such as gear rattle. Such vibro-impacts generally occur on the unloaded gear pairs of a vehicle correlated with the firing excitation of an engine...

.... 13 06 2013 05 02 2014 The present paper develops a nonlinear stiffness sensor for measuring cubic nonlinear elasticity. The measurement system consists of a vibrator with a control circuit. We apply linear-plus-nonlinear feedback to actuate the vibrator attached to a measurement object...

... in composite materials based on a measurement of the nonlinear forced response that damaged materials are assumed to exhibit. A damage feature was extracted for a structural component by quantifying the degree to which the reciprocity between two input-output structural paths fail due to the nonlinearities...

...A. Chakrabarti; P. C. Ray; Rasajit Kumar Bera This paper investigates the free out of plane vibration of a rotating nonhomogeneous beam with nonlinear spring and mass system. The effect of nonhomogeneity of the beam appears both in the governing equations and in the boundary conditions...
