In this thesis, the vibrational properties of composite plates with a cut are examined experimentally using a laser vibrometer and numerically using a finite element method. The samples are in the form of rectangular plates which are excited by random excitations of a shaker and are pounded upon by a laser jet which collects the displacements and feeds them to a data physics module which gives out the required displacement curves. The values obtained are verified theoretically using a finite element FORTRAN program. Orderly cuts of different dimensions along both directions of the fibers are made, the effect of such cuts on the vibration frequencies of the plate are studied, and the same have been verified using the program.
