The method proposed can be applied to the materials with high Possion's ratio and its numerical stability is good. Numerical simulations of elastic waves propagation in homogeneous and heterogeneous transversely isotropic media show that the elastic waves propagation in complex anisotropic media can be modeled effectively by this method and computation costs are very little.
A computer programme is designed for the wave propagation coefficient method, which is used to calculate the propagation coefficient and predict the wave propagating in the bar. As an example, the propagation coefficient of PMMA is calculated.
In the elastic stress wave region, a loading rate-dependent stress-strain relation for spherical stress wave propagating in granite has been obtained by means of Laprangian analyis of radial particle velocities measured in situ.
In this paper,non axisymmetric buckling of an elastic cylindrical shell,which is impacted on the end by axial step loads,is discussed with the aid of the stress wave propagating.
In this paper, non axisymmetric buckling of finite elastic cylindrical shell, which is impacted on the end by axial step loads, is discussed with the aid of the stress wave propagating and reflecting.
For wave propagation in dispersive media, the arrival time of the acoustic emission signal to the sensor is dependent on the setting of the threshold voltage, which results in the inaccuracy of the acoustic emission location.
The study of wave propagation in periodic systems is at the frontiers of physics, from fluids to condensed matter physics, and from photonic crystals to Bose-Einstein condensates.
In optics, a typical example of periodic system is a closely-spaced waveguide array, in which collective behavior of wave propagation exhibits many intriguing phenomena that have no counterpart in homogeneous media.
This class contains model equations of nonlinear waves propagation: the nonlinear Schr?dinger equation, the Korteweg--de Vries equation, and some others.
Crystal-lattice microdistortions in thermally treated steel IIIX15 are estimated via measurement of Rayleigh waves' propagation velocity by means of the technique based on speckle dynamic interferometry.
Stress waves propagation in the solid such as reflection, interference and diffraction was observed using polarized optics and an Imacon high speed camera (operating at both of 106 and 5×105 framing rates per second, fps).
It was found that stress waves propagation in solids depends not only on the surface geometry but also on the contact situation between liquid and solid.
Rock salt and limestone are studied to determine their suitability for use as a radio-wave transmission medium in an ultrahigh energy (UHE) cosmic neutrino detector.
A more than hundredfold increase in the nonreciprocity of electromagnetic wave transmission in a waveguide containing a transversely magnetized ferrite plate has been observed upon the introduction of a grating of bianisotropic elements.
The derived value of this velocity allows these structures to be identified as a fast magnetosonic wave propagating upstream of the solar wind inflowing the Earth's bow shock.
The gas motion is bounded, on the one hand, by a piston moving in accordance with an arbitrary law, and, on the other hand, by either a compression shock or a rarefaction wave propagating through the gas with given arbitrary parameters.
The solution of the problem of nonequilibrium ionization of dissociating air in a shock wave propagating with a speed of 5-10 km/sec has shown that the electron concentration distribution has a maximum behind the wave front for speeds below 9 km/sec.
The dispersion equation for the propagation of small perturbations is analyzed in the limiting cases of weak dispersion and of a wave propagating along the magnetic field.
The most significant property of a liquid mixture with gas bubbles is the compressibility of the latter under the influence of an externally applied pressure, for example, in a shock wave propagating in the liquid—gas medium.
