摘要：

The vibration of a laminated composite plate with closing delamination is analysed in the present paper using the finite element method. The effect of delaminated layers is modelled by using additional boundary conditions in the delamination front. Contact forces between delaminated layers are also considered in the model. The influence of delamination length and position on changes in natural frequencies of the plate is investigated. The plate is vibrated by a harmonic force or by a force impulse and the resulting time series are analysed using FFT. Results of the numerical calculations are compared against experimental data for laminated composite plates.
