This paper describes the delamination analysis of simply supported composite laminate plate in bending. The theoretical formulation is based on three plate model. The finite element method is used to analyse the laminate plate delamination, which is based on the theory of Midline plate and the eight-node is oparameter laminated plate element. The computer program for the determination of deformation and stress fields of composite laminate used to calculate the deflection at plate centre. The study includes the plate with and without delamination when effect by lamination angle, delamination area ratio and the location of the delamination along the thickness. Tsai-Hill criterion, Tsai-Wu criterion and Hoffman criterion are used to check the failure of the composite laminate. To investigate the first ply failure load, parametric studies are made for different cases by varying the size delamination as well as the stacking sequences. The results are presented in a tabular and graphical form showing the delamination area is directly proportional to the deflection at plate centre and the deflections of delamination plate are larger than deflections of perfect plate. |
