“…From the initial stage of the development of the aviation industry until now, the flutter problem of aircraft structures has always existed, and the investigations of aviation engineers on the flutter problem have never been stopped. The flutter problems of isotropic panels, 9,10 shells, 11–13 and wing structures 14,15 first attracted the attention of scientists. Based on the von Kármán large deformation and supersonic piston theories, Ye and Dowell 16 studied the limit cycle flutter of cantilever panels.…”

Flutter is a self-excited vibration under the interaction of the inertial force, aerodynamic force, and elastic force of the structure. After the flutter occurs, the aircraft structures will exhibit limit cycle oscillation, which will cause catastrophic accidents or fatigue damage to the structures. Therefore, it is of great theoretical and practical significance to study the aeroelastic characteristics and flutter control for improving the aeroelastic stability of aircraft structures. This paper reviews the recent advances in aeroelastic analysis and flutter control of wings and panel structures. The mechanism of aeroelastic flutter of wings and panels is presented. The research methods of aeroelastic flutter for different structures developed in recent years are briefly summarized. Various control strategies including the linear and nonlinear control algorithms as well as the active flutter control results of wings and panels are presented. Finally, the paper ends with conclusions, which highlight challenges of the development in aeroelastic analysis and flutter control, and provide a brief outlook on the future investigations. This study aims to present a comprehensive understanding of aeroelastic analysis and flutter control. It can also provide guidance on the design of new wings and panel structures for improving their aeroelastic stability.

“…Yang and Oyadiji [3] investigated the effects of delamination in LCBs due to concentrated mass loading with respect to modal frequency variations. The vibration and stability of rectangular plates in contact with fluid [4][5], vibration of elliptical and circular plates on an elastic foundation [6][7], laminated composite cylinder [8] and free vibration of Euler and Timoshenko LCBs based on finite strain displacement [9][10][11] have presented in the past researches.…”

In this study, a new closed-form solution for transverse free vibration analysis of laminated composite beams (LCBs) with arbitrary number of concentrated masses is developed. The LCB is modeled based on the Euler-Bernoulli beam theory and concentrated masses are simulated considering Dirac delta function.Obtained governing equations are, then, solved semi-analytically while the frequency equation and mode shapes are extracted for two different boundary conditions, i.e., clamped-free and simply-supported. In order to verify the closed-form solution, the represented model is simplified for a beam without concentrated mass and outcomes are compared with available results in the literature. Finally, the effects of mass as well as location and number of concentrated masses on the free vibration response of the beam are investigated in detail. The results highlight that with increasing the value of point masses, the natural frequencies decrease. Also, it was revealed that the number of point masses influences on the vibration of cantilever beam more than the simply-supported one. These outcomes would practically be used to minimize detrimental effects of vibrational noises, leading to increase of the structural components' lifetime.
