Then the eigenfrequencies and the eigenmodes of the fluid-solid structure are governed by the following variational eigenvalue problem (cf.
On the other hand its influence to the eigenfrequencies of the sample in our case low.
Muller has shown that a chain of similar harmonic oscillators generates a spectrum of eigenfrequencies, that can be expressed by a continued fraction equation [2]
1983; Wlazlo 1987) proved that appearance of cracks has significant impact not only on steel--concrete bond (Khalfallah 2008), deflection and redistribution of the internal forces, but also on the dynamic parameters, such as: eigenfrequencies and damping.
If the array of resonators is actuated by this signal so only those two resonators will start to resonate which eigenfrequencies are equal to the two frequency components in the input signal.
Poisson's ratio is the worst determined elastic characteristic of all because its influence on the eigenfrequencies of the specimen is sufficiently lower than other elastic characteristics and is difficult to measure by classical tests (Frederiksen 1998).
It is a typical situation that a vibrational device operates in one of its eigenfrequencies and with the change of eigenforms sequence the numerical analysis becomes meaningless as the solution usually does not converge.
In the most general case, the spectrum of eigenfrequencies of a chain system of many proton harmonic oscillators is given by the continuous fraction equation [2]
The final goal of this work is a design of an artificial cochlea which is compound from set of resonant beams with different eigenfrequencies.
