Summary
The propagation of harmonically time-dependent electromagneto-thermoelastic plane waves of assigned frequency in an unbounded, homogeneous, isotropic, elastic, thermally and electrically conducting medium is considered. The theory of thermoelasticity recently proposed by Green and Lindsay is used to account for the interactions between the elastic and thermal fields. The results pertaining to phase velocity and attenuation coefficient of various types of waves are compared with those of Nayfeh and Nemat-Nasser who have dealt with a theory of thermoelasticity having a thermal relaxation time.
Zusammenfassung
Die Fortpflanzung von harmonischen, zeitabhängigen, elektro-magnetothermoelastischen ebenen Wellen von gegebener Frequenz in einem unbegrenzten, homogenen, isotropischen, elastischen, wärme- und elektrisch leitendem Material wird behandelt. Die Wechselwirkung zwischen den elektrischen und thermischen Feldern wird durch die kürzlich vorgeschlagene Thermoelastizitätstheorie von Green und Lindsay beschrieben. Die Dämpfungskoeffizienten der verschiedenen Wellentypen werden mit denen von Nayfeh und Nemat-Nasser verglichen, welche schon früher eine Thermoelastizitätstheorie mit thermischer Relaxationszeit behandelt hatten.
