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)
“Well designed, fully functional infant. Provides someone to live for as well as another mouth to feed. Produces cooing, gurgling and other adorable sounds. May cause similar behavior in nearby adults. Cries when hungry, sleepy or just because. Hand Wash with warm water and mild soap, then pat dry with soft cloth and talc.

“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 (1889–1951)
