In this paper presents an experimental and numerical investigation of the natural frequency of composite material cantilever plates. The stacking sequence of the composite plate is Quasi-isotropic laminated plate is [2(0°)/±45°/2(90°)]s. The plate was subjected to incremental cuts and tests to determine changes in new modal properties. The study included white noise and sinusoidal dynamic testing techniques and a virtual instrument dynamic analyzer. In this study also, determining the resonant frequencies of the undamaged and damaged plate, and evaluating the capabilities of piezoelectric ceramics (PZT's) for fault detection based on their sensitivity and accuracy changes in modal parameters. Numerical results are obtained using finite element software for the composite materials plates. The experimental and numerical results are very good agreement for the composite material cantilever plates with and without damage.
