The purpose of this thesis is to demonstrate the use of boundary element techniques for the dynamic analyses of geometrically repetitive structures using the traveling wave approach. A formulation of the boundary element method BEM for 2-D isotropic materials is developed. The BEM formulation is then used to calculate the mass and stiffness matrices of one bay of a baseline structure. From the mass and stiffness a transfer matrix is developed for the bay. Using traveling wave theory, the transfer matrix is then used to identify the dynamical characteristics of a multiple bay structure. Results are compared to continuum theory.
