Modal testing of structures with closely coupled modes is a task performed very frequently. On many occasions, structures have modes that possess very similar resonant frequencies. In one such case, a ...
Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...
