Abstract The fatigue life of adhesively bonded scarf joints with various scarf angles was analyzed experimentally in this study. Experimental results indicate that the fatigue strength increases significantly with the scarf angle of the studied specimen. The main failure modes for the specimens with small and large scarf angles are adhesive and cohesive, respectively. Additionally, the finite element method was employed to obtain the stress states within the studied scarf joint specimens, and th...
The present paper is concerned with a phenomenological model to perform the failure analysis of composite adhesive single lap joints with arbitrary glued area. The theory is conceived for joints composed by highly resistant elastic adherends bonded with brittle–elastic adhesives. It is shown that, under certain conditions, the rupture forces (in the case of monotonic loading) and lifetimes (in the case of cyclic loading) of two joints with different glued areas can be correlated using a shape fa...

In this paper, a new nano-adhesive which has been improved the conventional epoxy resin that is widely used in the automobile industries was introduced. Multi-walled carbon nano-tubes (MWCNTs) (1%-3% by weight) were mixed into epoxy resin using a mixer. The bubbles generated during the mixing processes were removed using a high vacuum. In order to optimize the quality and performance for actual application, the mechanical properties of the joints taking into account the geometrical parameters of...

Abstract In this paper, the fatigue response of adhesively bonded joints under variable amplitude (VA) cyclic loading was predicted using a numerical model. The adhesive layer was modelled using the cohesive zone model with a bi-linear traction-separation response. A damage model, incorporating fatigue load ratio effects, was utilised in conjunction with the cohesive zone model to simulate the detrimental influence of VA fatigue loading. This model was validated against published experimental re...

The use of edge-bond adhesive is recently found to be a possible alternative to underfill for solder joint protection. This paper investigates the effectiveness of using it for the enhancement of solder joint thermal fatigue reliability. Both the accelerated temperature cycling (ATC) test and simulation are performed for the study. The test vehicle is a 51×51 mm ceramic ball grid array (CBGA) package. There are three batches of samples prepared. One of them utilizes no edge-bond and the other tw...
This study is focused on the static and fatigue strength of interference-fitted connections supplemented with anaerobic adhesive (hybrid joints). Through axial release tests, it is demonstrated that the addition of the adhesive always improves the performance of the joint. The main achievable benefits can be summarized in (a) the possibility of increasing the load transfer capability with the same joint geometry and (b) reducing both the weight and the stress field of the joint with the same loa...
Abstract The shear fatigue lives of Anisotropic Conductive Adhesive Film (ACF) joints were evaluated experimentally and theoretically under different testing conditions. The shear fatigue tests of ACF joints were performed with different loading amplitudes. It is found that the fatigue lives of ACF joints decrease with increasing loading amplitudes and Basquin’s equation is fit to predict the fatigue lives of ACF joints. Hygrothermal aging and thermal cycling tests were conducted to investigate ...
Abstract Experimental investigation on fatigue behavior of carbon–epoxy composite bonded joints under mode I loading was performed in this work. The objective is to evaluate the performance of different data reduction schemes to obtain the energy release rate ( G I ) in the fatigue crack growth (FCG) rate using double cantilever beam (DCB) specimens. This law relates the evolution of the crack along time as a function of the energy release rate ( G I ) and is generally composed of three differen...

Friction spot joining is an alternative technique for joining metals with polymers and composites. This study investigated the fatigue performance of aluminum alloy 2024/carbon-fiber-reinforced poly(phenylene sulfide) joints that were produced with friction spot joining. The surface of the aluminum was pre-treated using various surface treatment methods. The joined specimens were tested under dynamic loading using a load ratio of R = 0.1 and a frequency of 5 Hz. The tests were performed at diffe...
The T-90 Calima is a low-wing monoplane aircraft. Its structure is mainly composed of different components of composite materials, which are mainly bonded by using adhesive joints of different thicknesses. The T-90 Calima is a trainer aircraft; thus, adverse operating conditions such as hard landings, which cause impact loads, may affect the structural integrity of aircrafts. As a result, in this study, the mode I crack propagation rate of a typical adhesive joint of the aircraft is estimated un...

Abstract The tension-tension fatigue behavior of ductile adhesively-bonded double-lap FRP joints was experimentally investigated. An acrylic adhesive, which was in the rubbery state at ambient temperature, provided the joint ductility. The fatigue degradation of the joints was characterized by the cyclic energy dissipation, cyclic stiffness, cyclic creep displacement and self-generated temperature. The effects of elevated temperature on the joints’ static tensile and pure creep behaviors were al...
