TB 26-08 Complex Modes in Lightly Damped Structural Systems: A Two-Mode Interaction Perspective
For more information, contact Joel W. Sills, Langley Research Center, [email protected] Download the PDF version Complex mode shapes can emerge in a linear structure even when overall damping is low. This behavior can occur when two structural modes are closely spaced in frequency and are coupled through nonproportional damping. As the damping interaction increases, the […]
