Reflection of Plane Waves at Micropolar Piezothermoelastic Half-space

Abstract

A problem of reflection at a free surface of micropolar orthotropic piezothermoelastic medium is discussed in the present paper. It is found that there exist five type plane waves in micropolar orthotropic piezothermoelastic medium, namely quasi longitudinal displacement wave (quasi LD wave), quasi thermal wave (quasi T wave), quasi CD-I, quasi CD-II wave and electric potential wave (PE wave). The amplitude ratios corresponding to reflected waves are obtained numerically. The effect of angle of incidence and thermopiezoelectric interactions on the reflected waves are studied for a specific model. Some particular cases of interest are also discussed.

Kumar et al [10] studied the reflection of a plane wave in an orthotropic piezothermoelastic micropolar medium. Zenkour [11] studied the thermomechanical response of microbeams with Refined two-temperature MPL theory and the modified couple stress analysis.…”
