The research reported is the study of the transmission and reflection characteristics of flexural waves at structural discontinuities. A Fast Fourier Transform (FFT) computer algorithm is used to characterize the dispersive flexural waves. The incident wave is propagated through two types of discontinuities namely, a stepped beam and the free end of a beam. At each stage, comparison with experimental results are made.
