Flutter Induced By Dry Friction
It may seem surprising that aeroelastic flutter is a phenomenon sharing similarities with instabilities due to friction. This was recently experimentally discovered by Bigoni and Noselli (2011), who have produced a follower force through dry friction at the contact between two sliding bodies, see the animation on the right and watch a movie for more details.

Famous quotes containing the words flutter, induced, dry and/or friction:
“Scarlet, and blue, and snowy white,
The guidon flags flutter gaily in the wind.”
—Walt Whitman (1819–1892)
“It is a misfortune that necessity has induced men to accord greater license to this formidable engine, in order to obtain liberty, than can be borne with less important objects in view; for the press, like fire, is an excellent servant, but a terrible master.”
—James Fenimore Cooper (1789–1851)
“I have this very moment finished reading a novel called The Vicar of Wakefield [by Oliver Goldsmith].... It appears to me, to be impossible any person could read this book through with a dry eye and yet, I don’t much like it.... There is but very little story, the plot is thin, the incidents very rare, the sentiments uncommon, the vicar is contented, humble, pious, virtuous—but upon the whole the book has not at all satisfied my expectations.”
—Frances Burney (1752–1840)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
