Abstract: | The influence of the viscosity on reflection and refraction of plane shear elastic waves in two magnetized semi-infinite media
is investigated. The numerical results for the absolute values of the reflection and refraction coefficients and their relative
changes for a particular choice of the media are presented graphically. The relative changes of these coefficients are calculated
for two special orientations of the magnetic field. It is found that the absolute values of these coefficients are not only
functions of the angle of incidence but they are also functions of both the large primary magnetic field and the viscosity
of the media. They also vary with the orientation of the magnetic field. Finally, we show that the results of earlier works
could be obtained here as particular cases. Finally, this study is regarded an attempt to accommodate magnetic field in visco-elastic
media where reflection and refraction of plane shear waves are considered. Results which are obtained in this investigation
useful for practical applications or for understanding some aspects of physical acoustic. |
