Aeroelastic analysis and flutter control of wings and panels: A review
International Journal of Mechanical System Dynamics, 2021 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 ...

Thinner biological tissues induce leaflet flutter in aortic heart valve replacements
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Percutaneous valve replacement procedures enable the deployment of bioprosthetic heart valves through a catheter, which offers a minimally invasive option to treat valvular heart disease. Although these bioprostheses typically employ thinner
