This study evaluates the effects of the overlap length and different adherend materials with different thicknesses on the mechanical performance of the bolted (BJ), adhesively bonded (ADJ) and hybrid joints (HJ) subjected to quasi-static axial tensile loading. The three different joints were fabricated and tested according to 36 different variances, including two kinds of adherend materials (AL6061 and Al7075 with different yield strength, tensile strength and ductility values), three adherend thicknesses (2 mm, 4 mm and 6 mm) and two overlap lengths (25 mm and 45 mm). Numerical models were implemented and developed using the commercial software Abaqus/Explicit. The adhesive layer (AF163-2K) was simulated by using cohesive interface elements with traction-separation response. Ductile/shear damage models were used to simulate the failure behavior of the adherends and the bolt material. To interpret the strength of various joints, failure behavior for each configuration is analyzed widely. [ABSTRACT FROM AUTHOR]

The tensile properties of a pressure-sensitive adhesive tape which can be cured to impart structural performance have been measured at different temperatures using quasi-static tests. In order to assess the linear viscoelastic behaviour of the tape, results from the vibrating beam technique are also presented. Bulk specimens and non-contacting extensometers were found to be suitable for tensile measurements on such a flexible adhesive. The results show that the strength of the tape is not as high as, and that its behaviour is very different from, traditional structural adhesives, but its high strain-to-failure with an adequate strength offers exciting possibilities for structural joints.
