... Green’s function Impulsive point source Functionally graded Phase velocity Piezoelectricity refers to the ability of certain crystals to respond electrically to mechanical stress and generate mechanical strain when an electric field is applied. Due to its widespread application in several...

... and the interfaces of the expressed medium. The adopted numerical examples are used to compute the dispersion relation and plot the graphs between phase/damped velocity and wave number. Parametric studies on the phase and damped velocity yield five main conclusions: (1) Phase velocity decreases with increasing value...

... and poroelastic medium. All the constituents here are assumed to be dissipative, heterogeneous and initial stressed. Findings Phase velocity and attenuation are computed against wavenumber for various values of self-reinforcement parameter, inhomogeneity parameter and initial stress. Particular cases...
