The extensive use of adhesives in many structural applications in the transport industry and particularly in the aeronautic field is due to numerous advantages of bonded joints. However, still many researchers are working to enhance the mechanical properties and rheological performance of adhesives by using nanoadditives. In this study the effect of the addition of Multi-Wall Carbon Nanotubes (...

An adhesive-bonded single lap joint is analyzed using a new fuzzy finite element model. In the model, Young’s moduli and Poisson’s ratios of the joint materials are taken as fuzzy numbers in order to take the uncertainty of the material properties into account. The fuzzy numbers are modeled using linear triangular membership functions. At a selected material point in the adhesive layer, the pos...

In this presentation, the structural performance of fiber reinforced composite laminate Pi joints is studied through a progressive failure analysis (PFA) method. The bonded joint area that is the weakest link of the Pi joint structure is modeled using the discrete cohesive zone method (DCZM). The damage growth and failure of the bonded interface is modeled through an exponential decaying tracti...

Large free-edge interfacial stresses induced in adhesively bonded joints (ABJs) are responsible for the commonly observed debonding failure ABJs. Accurate and efficient stress analysis of ABJs is important to design, structural optimization, subjected external mechanical thermomechanical loads. This paper generalizes high-efficiency semi-analytic stress-function variational methods developed by...

This research presents the interaction of the epoxy polymer diglicydil ether of bisphenol-A (DGEBA) with silica (SiO₂) nanoparticles plus zirconia (ZrO₂) nanoparticles obtained via the sol-gel method in the synthesis of an epoxy-silica-zirconia hybrid adhesive cured with polyamide. ZrO₂ nanoparticles were added to the epoxy-silica hybrid adhesive produced in situ to modify the apparent shear st...

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with uni-directional glass fibers. Epoxy adhesive impregnated fiber were used to join composite plates joints. It is aimed strengthen the joint by layers between two plates. The loads of obtained compared attached non-reinforced adhesive. Also, 0o, 15o 30o and 45o re...
