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:
“After the brief bivouac of Sunday,
their eyes, in the forced march of Monday to Saturday,
hoist the white flag, flutter in the snow storm of paper,”
—Patricia K. Page (b. 1916)
“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 (17891851)
“I can love both fair and brown;
Her whom abundance melts, and her whom want betrays;
Her who loves loneness best, and her who masks and plays;
Her whom the country formed, and whom the town;
Her who believes, and her who tries;
Her who still weeps with spongy eyes;
And her who is dry cork, and never cries.
I can love her, and her, and you and you,
I can love any, so she be not true.”
—John Donne (15721631)
“We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk so we need friction. Back to the rough ground!”
—Ludwig Wittgenstein (18891951)
