Abstract: The symmetric monostable Duffing oscillator exhibits a superharmonic resonance of order three when excited harmonically at an excitation frequency that is one third its linear natural frequency. In this letter, it is shown ...

Abstract: This paper describes a new parametric method for the development of nonlinear models with parameters identified from an experimental setting. The approach is based on applying a strong nonresonant high-frequency harmonic ...

Abstract: This paper investigates the response of a bistable energy harvester to random excitations that can be approximated by a white noise process. Statistical linearization (SL), direct numerical integration of the stochastic ...

Abstract: Vibrational resonance (VR) is a nonlinear phenomenon which occurs when a bistable system is subjected to a biharmonic excitation consisting of a small-amplitude resonant excitation and a large-amplitude high-frequency ...

Abstract: This paper develops and validates an aeroelectromechanical model which captures the nonlinear response behavior of a piezoelectric cantilevertype energy harvester under combined galloping and base excitations. The harvester ...

Abstract: This paper investigates the influence exerted by small surface tension on the nonlinear normal sloshing modes of a two-dimensional irrotational, incompressible fluid in a rectangular container. To this end, the influence ...

Abstract: The adaptation of engineered structures and systems to suit the working environment has historical precedents dating to da Vinci's sketches of regulating pumps and balancing devices [1]. Systems that respond to changing ...

Abstract: The objective of this paper is twofold: first to illustrate that nonlinear modal interactions, namely, a twotoone internal resonance energy pump, can be exploited to improve the steadystate bandwidth of vibratory energy ...

Abstract: To begin, we would like to point out that the complexity of the response behavior of nonlinear harvesters as compared to their linear counterparts remains the biggest challenge preventing us from optimizing their performance ...

Abstract: The last two decades have witnessed several advances in microfabrication technologies and electronics, leading to the development of small, lowpower devices for wireless sensing, data transmission, actuation, and medical ...
