Reflection of transverse and microrotational waves from free surface in micropolar thermodiffusion elastic half-space

Kumar R., Kaushal S., Sharma K. D., Garg S. K.

International Journal of Applied Mechanics and Engineering

2012

Vol. 17, no. 2

401-417

The problem of reflection of plane waves in a micropolar thermodiffusion elastic is investigated in the context of the coupled theory. The amplitude ratios of various reflected waves are continuous functions of the angle of incidence and material parameters of the medium. A graphical representation of amplitude ratios is presented and the impact of micropolarity and diffusion property of the medium is observed to be significant. Some special cases of interest are deduced from the present article.

Reflection and refraction of quasi-SV waves at the interface of the monoclinic media

Chattopadhyay A., Saha S.

Acta Geophysica Polonica

1999

Vol. 47, nr 3

307-322

Reflection and refraction phenomena of quasi-SV waves at a plane interface of two monoclinic half-spaces have been discussed. It has been pointed out that due to incident quasi-SV wave in a monoclinic medium, the three types of waves exist: quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH). The reflection and refraction coefficients for qP, qSV and qSH waves have been computed. The effects due to the crystalline nature of the medium have been distinctly marked. The results are presented graphically and compared with the isotropic case.
