Investigation on the Influence of Adhesive Characteristics in Buckling Load of a Stiffened Laminated Composite Plate

Secondary bonding of stiffeners is regarded as a method of integrating stiffened composite plates. In present research, the effects of adhesive layer parameters of flange-plate adhesive joint, including adhesive layer thickness and its material properties, in buckling load of a stiffened laminated composite plate, are studied. Modeling is prepared by means of ABAQUS finite element software. Results of eigenvalue problem show that, magnitudes of fundamental and secondary buckling loads are enhanced by increase in the thickness and stiffness of adhesive layer. Furthermore, investigations are also done on the effect of discrete adhesive bonding method. Open-section stiffeners such as I- and J-type will be implemented other than blade-type stiffener as well.
