The vibration of plates is a special case of the more general problem of mechanical vibrations. The equations governing the motion of plates are simpler than those for general three-dimensional objects because one of the dimensions of a plate is much smaller than the other two. This permits a two-dimensional plate theory to give an excellent ...
Ernst Florens Friedrich Chladni (UK: / ˈklædni /, US: / ˈklɑːdni /, German: [ɛʁnst ˈfloːʁɛns ˈfʁiːdʁɪç ˈkladniː]; 30 November 1756 – 3 April 1827) was a German physicist and musician. His most important work, for which he is sometimes labeled the father of acoustics, included research on vibrating plates and the calculation ...
A demonstration of sand forming cymatic patterns on a metal plate. Cymatics (from Ancient Greek: κῦμα, romanized: kŷma, lit. 'wave') is a subset of modal vibrational phenomena. The term was coined by Swiss physician Hans Jenny (1904–1972). Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and ...
The Reissner–Mindlin theory of plates is an extension of Kirchhoff–Love plate theory that takes into account shear deformations through-the-thickness of a plate. The theory was proposed in 1951 by Raymond Mindlin. [1] A similar, but not identical, theory in static setting, had been proposed earlier by Eric Reissner in 1945. [2]
Through the George E. Brown, Jr. Network for Earthquake Engineering Simulation (), researchers are studying the performance of base isolation systems. [16]The project, a collaboration among researchers at University of Nevada, Reno; University of California, Berkeley; University of Wisconsin, Green Bay; and the University at Buffalo is conducting a strategic assessment of the economic ...
v. t. e. Vibration mode of a clamped square plate. In continuum mechanics, plate theories are mathematical descriptions of the mechanics of flat plates that draw on the theory of beams. Plates are defined as plane structural elements with a small thickness compared to the planar dimensions. [1] The typical thickness to width ratio of a plate ...
The EMT 140 plate reverb system. A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibrations in a large plate of sheet metal. The plate's motion is picked up by one or more contact microphones whose output is an audio signal which may be added to the original "dry" signal. [3]
Arthur Leissa went to the Ohio State University as an undergraduate, earning bachelor's and master's degrees in mechanical engineering in 1954. He worked for a year in industry before returning to Ohio State for doctoral studies. He completed his Ph.D. in 1958, and remained at Ohio State as a faculty member. At the time of his promotion to full ...
