Numerical Study of Characteristic Equations of Thermoelastic Waves Propagating in a Uniaxial Prestressed Isotropic Plate

Figure 6

Frequency spectra of (a) the phase velocity and (b) the semilogarithmic plot of attenuation for the symmetric modes (red lines) and antisymmetric modes (black lines) of a thermoelastic wave propagating along the -direction in the copper foil under the natural state (without any prestress) and two initial states with two uniaxial prestresses and applied in the -direction.
