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 (1789–1851)
“If you are one of the hewers of wood and drawers of small weekly paychecks, your letters will have to contain some few items of news or they will be accounted dry stuff.... But if you happen to be of a literary turn of mind, or are, in any way, likely to become famous, you may settle down to an afternoon of letter-writing on nothing more sprightly in the way of news than the shifting of the wind from south to south-east.”
—Robert Benchley (1889–1945)
“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)
