In nondestructive testing ultrasound waves are an important tool for inspection of voids and faults in materials. The method is well established for isotropic and homogeneous materials whereas cases with anisotropy and inhomogeneity lead to difficulties in the design of inspection procedures and interpretations of inspection results. The difficulties arise from redirection and/or bending of the sound wave propagation in an unknown manner. In order to investigate the influence of anisotropy and inhomogeneity on the sound wave propagation we have implemented the elastic wave equations using Elasto Dynamics Finite Integration Technique (EFIT).
