Abstract

In this paper, the wave field has been computationally modeled in the anisotropic plate. The Christoffel’s equation is solved to calculate the phase velocity of different wavefronts present at any point in the problem geometry. The calculated phase velocity is then used to develop the Green’s function. The anisotropic Green’s function was developed by implementing Radon transform and Spectral theorem into governing elastodynamic equation. Then the wave behavior in the anisotropic plate is simulated and studied by instigating the calculated Green’s function into the computational non-destructive evaluation (CNDE) technique, distributed point source method (DPSM). The wave propagation with different actuation angles for the transducer are simulated in plate with various forms of anisotropy such as transversely isotropic, orthotropic and, monoclinic plate. The study was performed such that the different anisotropic wave behaviors can be understood to the maximum extent in simplest form. The actuation angle used is normal incidence angle from the perpendicular to problem geometry surface with the actuation frequency of 1MHz. MATLAB is used for coding and simulation.
