NASA reports: Sills, Langley Research Center, joel.w.sills@nasa.gov Download the PDF version Complex mode shapes can emerge in a linear structure even when overall damping is low.
For more information, contact Joel W. This behavior can occur when two structural modes are closely spaced in frequency and are coupled through nonproportional damping.
This science story centres on the United States. Names and organisations mentioned in the coverage include Complex Modes, TB and Lightly Damped Structural Systems.
Why it matters
Research developments are often early steps — further studies typically determine how significant they prove to be.
