Propagation of Quasi-Vertical Transverse Waves Between Tow Piezothermoelastic Media on the Theory of Lord and Shulman Context under Initial Stresses Influence(View Complete Item Description)
The governing equations for two-dimensional generalized thermoelastic model in piezoelectric media under initial stresses effect by applying suitable conditions are solved. The generalized theories of piezothermoelasticity have been used to investigate the problem. In this model, there are four types of plane waves quasi-vertical transverse (QSV), quasi-longitudinal (QP), thermal wave (T-mode), and potential electric waves (j-mode). The closed-form expressions for the reflection and refraction coefficients for various reflected and refracted waves are obtained. These reflection and refraction coefficients are found to depend upon the angle of incidence of SVwave, thermoelastic, piezoelectric parameters and other material constants. The numerical values of modulus of the reflection and refraction coefficients are presented graphically for different initial stress and thermal relaxation time values.
