During the past few decades, several significant progresses have been made in exploring
complex nonlinear dynamics and vibration suppression of conceptual aeroelastic airfoil …

In the last few decades, there has been an increasing interest in the field of nonlinear
aeroelasticity. With substantial improvements in computing capabilities, the control surface …

This paper presents a review and assessment of more than six decades of research in
aeroelastic stability, including control-surface nonlinearities. The work covers free play …

In this work, we study how a contact/impact nonlinearity interacts with a geometric cubic
nonlinearity in an oscillator system. Specific focus is shown to the effects on bifurcation …

Aeroelasticity exists in airfoil with control surface freeplay, which may induce instability in an
incompressible flow. In this paper, a nonlinear energy sink (NES) is used to suppress the …

Impact oscillators frequently appear in various physical and engineering systems with non-
smooth characteristics and can exhibit different dynamic behavior from the smooth nonlinear …

The present study focuses on investigating the bifurcation characteristics of a pitch–plunge
aeroelastic system possessing coupled non-smooth nonlinearities, both in structural and …

Dynamical systems subject to intermittent contact are often modeled with piecewise-smooth
contact forces. However, the discontinuous nature of the contact can cause inaccuracies in …

Most of the previous studies on free-play aeroelasticity were based on the linear
aerodynamic theory, which cannot consider the aerodynamic nonlinear effects. This paper …

Freeplay is a significant source of nonlinearity in aeroelastic systems and is strictly regulated
by airworthiness authorities. It splits the phase plane of such systems into three piecewise …
