Sound field distribution influenced by anisotropic materials
- Bundesanstalt fuer Materialforschung und -pruefung, Berlin (Germany)
Sound wave distributions in isotropic materials are often described using analytical or numerical solutions of the wave equation. In opposition to this, it is more difficult to find a solution for anisotropic mediums. One possible method is the elastic finite integration technique (EFIT). With this method, scalar and vectorial calculations of the sound distribution from a line source in anisotropic materials were carried out. This method needs a powerful computer in order to keep the computation time short. In the present paper another theoretical model was used -- the pulse integration model -- with which sound field distributions for scalar waves were calculated in the sound field distribution of longitudinal waves in anisotropic materials. The principle of the model is described briefly. Different sound field pattern generated with a phased array longitudinal wave probe were calculated during the propagation in a homogeneous isotropic material and in a homogeneous anisotropic material (single crystal).
