WebTracing the family tree of plate theory to its roots, one travels back to the American Revolution time period and finds Euler performing free vibration analyses of plate problems (Euler, 1766). Chladni, a German physicist, performed experiments on horizontal plates to quantify their vibratory modes. He sprinkled sand on the plates, WebDescription. Chladni patterns. This experiment involved analyzing the Chladni patterns both qualitatively and mathematically. Stationary waves were formed as the plate vibrates and produced exquisite patterns. The …

WebOct 1, 2024 · Section snippets Axisymmetric vibrations of a circular plate completely free. Leissa (1969) and Leissa and Narita (1980) calculated the natural frequencies of circular plates in a vacuum by solving the classical differential equation of motion for the transverse displacement of a plate given by D ∇ 4 w + ρ A ∂ 2 w ∂ t 2 = 0 where ρ A is the area …
Chladni's law, named after Ernst Chladni, relates the frequency of modes of vibration for flat circular surfaces with fixed center as a function of the numbers m of diametric (linear) nodes and n of radial (circular) nodes. It is stated as the equation where C and p are coefficients which depend on the properties of the plate.
