Abstract: A finite element approach is presented in this study to analyze the free vibration of square and circular composite plates with delaminations around internal cutouts. Numerical examples including composite plates with delaminations around circular holes or square cutouts are presented. The effects of the cutouts and the delaminations around the cutouts on the natural frequencies and mode shapes are discussed. It is found that the effect of the delamination on the natural frequencies is mode-dependent. In certain cases, delaminations may have significant effect on some natural frequencies, even though the mode shapes of the plates are not significantly affected by the delaminations. © 1995.
