Aeroelasticity
Definition
A branch of mechanics and aerospace engineering that studies the interactions between aerodynamic forces, the elastic forces of a solid body's structure, and its inertial forces, while in relative motion. This field is crucial in the design of high-speed aircraft and suspended bridges to prevent destructive structural instability phenomena, such as flutter or buffeting.
