The most frequent failure mode of composite plates is delamination. Deboning between the adjacent layers at a particular region of the multilayered composite plate is consider as delamination. It is due to a defect in the manufacturing practice or can be caused by service time conditions, for example, impact by foreign objects. Overall Stiffness of the composites reduces due to delamination. This paper presents the effect on natural frequency due to the delamination of the fiber-reinforced plastics (FRP) composites. In the finite element method, delamination is implemented as a VCCT or cohesive zone method, but in this article, delamination modeled as an open area in the interface layer in ANSYS ACP (pre).Numerical and experimental modal analysis is performed to delaminate as well as intact composite plates. Extract modal parameters like natural frequencies and mode shapes from the modal analysis. The results of the present paper compare among the existing simulation results and observe that good agreement between them. also, study the variation of frequencies with an increase of delamination. The new proposed modeling of delamination is simple and gives accurate results. This method is also used tostudy the delamination effect in composite plates.
