Abstract :In this study, a boundary element formulation having nonlocal boundary conditions is presented for the dynamic analysis of a two-phase composite. Nonlocal boundary conditions, used in the formulation, make it possible to analyze a three-phase composite. The formulation is performed in Fourier transform space using a constant element model. Based on the formulation presented in this study, two general purpose computer programs are developed, namely, CD2NL insert ignore into journalissuearticles values(for two-dimensional analysis); and CD3NL insert ignore into journalissuearticles values(for three-dimensional analysis);. The programs perform the analysis in Fourier transform space and can also be used for static analysis by assigning a small value to the frequency. The results of some benchmark problems obtained using the programs are compared with those in the literature.
