Investigation of surface acoustic waves in solid

In this work, firstly, we explained some parameters such as stress, strain, Hooke's law, the Cy elastic coefficients and the Christoffers equations which are important parameters for propagating waves in solids. Then, we obtained the solutions in the [100] and [110] directions for anisotropic medium and also isotropic medium. Furthermore, acoustic surface wave is expressed. Hence, the solutions for acoustic surface waves in cubic crystals in the [100] and [110] directions are obtained. In chapter three, we explained the way of solution of the equation of surface wave by using Mathematica 4.0 packet program. Finally, in the last chapter, the data obtained by using Mathematica 4.0 packet program are investigated.
