IN THE THEORY OF AN ELECTRO-MICROSTRETCH

GENERALIZED THERMOELASTIC SOLID

The present article deals with the study of propagation of plane wave and
fundamental solution in an electro-microstretch generalized thermoelastic solid. It is found
that for two dimensional model, there exist three coupled longitudinal waves, namely
longitudinal displacement wave (LD-wave), thermal wave (T-wave), longitudinal
microstretch wave (LM-wave) and two coupled transverse displacement and transverse
microrotational (CD I, CD II) waves. The phase velocity, attenuation coefficient, specific loss
and penetration depth are computed numerically and depicted graphically. In addition, we
construct the fundamental solution of the system of differential equations in the theory of an
electro-microstretch generalized thermoelastic solid in case of steady oscillations in terms of
elementary functions. Some basic properties of the fundamental solution are established.
Some special cases are also discussed.
Keywords: steady oscillations; electro-microstretch; phase velocity; attenuation coefficient; fundamental solution |
