Longitudinal waves in an elastic body in which the derivative of the stress with respect to the strain (the coefficient of elasticity) can undergo a discontinuity are considered. Fronts can be propagated in such a body, in which a jumplike change in the coefficient of elasticity and the ...
英语翻译A longitudinal wave causes the particles of a medium to move parallel to the direction of the wave.Figure 15-2b shows a longitudinal wave .Note that the motion of the spring is parallel to the direction in which the wave is moving .Thus t
Purpose of this paper is to study the evolution of longitudinal strain waves in the walls of an annular channel filled with a viscous incompressible fluid. The walls of the channel were represented as coaxial shells with fractional physical nonlinearity. The viscosity of the fluid and its influence...
A homogeneous isotropic compressible Hadamard material has the property that an infinitesimal longitudinal homogeneous plane wave may propagate in every direction when the material is maintained in a state of arbitrary finite static homogeneous deformation. Here, as regards the wave, 'homogeneous' means ...
Longitudinal waves in a dusty plasma are studied using fluid models where we regard the dust as being immobile. The variation of the charge on the dust particles due to the wave field is taken into account. Three wave modes are considered; the ionacoustic wave, the electrostatic ion cyclotron...

The interaction of electromagnetic radiation with a time-switched magnetoplasma is considered. Exact analysis, including ion motion, for longitudinal propagation is given. The original wave splits into four new waves whose frequencies are different from the incident wave frequency. Approximate dispersion ...
In a partially ionized gas, two longitudinal wave modes propagate at high frequencies, the ion゛coustic mode and the neutral゛coustic mode. At very low frequencies, there are also two roots of the dispersion relation, one representing a damped wave and one representing an undamped wave. If the...
This means that the particles of the medium are moving back and forth in the same direction that the wave is traveling. How are longitudinal waves created in air? Longitudinal waves in air are created by a disturbance, such as a vibrating object, that causes the air particles to com...
