This thesis is aimed to analyse the mode of failure of selected fiber reinforced composite plates under transverse loading. A mathematical model and computational model are presented for the analysis. Higher Order Shear Deformation plate theory is utilised to predict the deformation of the plates. A failure criterion with the existence of coupling terms is employed to predict the failure. A program based on a finite element method is developed using Fotran-90 to determine the lamina stresses. These stresses are then used in the present failure model to determine the Mode of Failure. Finally, the Mode of Failure results for Glass Epoxy composite plates are analysed. The results of the mode of failure analysis have shown that the present failure models could offer a better prediction of failure for any composite laminate. The results could also aid in designing optimum composite laminates.
