Abstract

The problem of reflection and transm ission of plane waves incident on the contact surface of an elastic solid (medium M) and electro-micro stretch generalized thermoe lastic solid (medium M), was discussed. It is found that there exist five reflected waves (longitudinal displacement (LD) wave, thermal (T) wave, longitudinalm icrostretch (LM) wave and two coupled transverse displacement and microrotational (CD(Ⅰ) and CD (Ⅱ) waves)) in medium Mand two transmitted waves (longitudinal (P) and tran sverse (SV) waves) in medium M. The amplitude ratios of different reflected and transmitted waves were obtained for an miperfect boundary, and deduced fo r no rm al fo rce stiffness, tran sverse force stiffness and perfect bond ing. The variations of am plitude ratios with angle of incidence were depicted graphically for LD-wave, and CD(Ⅰ)-wave. It is noticed that the am plitude ratios of reflected and transmitted waves are affected by stiffness, electric field, stretch and thermal properties of the media. Some particular cases of interest were deduced from the present investigation.
- amplitude ratios,
- electro-microstretch thermoe lastic solid,
- normal force stiffness,
- transverse force stiffness,
- welded contact
