“…When the degradation factors were combined, with UV exposure and continuous condensation at 40 °C, in addition to mixed failure, adherend failure mode also started to occur. The change in failure mode due to exposure to environmental factors, such as temperature, humidity and UV radiation, has also been observed by other researchers, such as Zheng et al [1], Khaleel et al [58], Giampaoli et al [165] and Zheng et al [156]. In general, the results reported by these authors indicate that the optimum design of an adhesive bonded joint is dependent on understanding the failure modes of the system, since these are sensitive to the environmental and loading conditions imposed.…”

“…Several studies have been conducted to understand the behavior of joints under loading conditions, such as static and dynamic loads [1,31,51,58,[64][65][66][67][68]. In these works, the authors report that the effective length of the overlap is influenced by the type of loading and the applied loading rate.…”

“…The temperature can be high, moderate, low or variable in cycles, and each of these conditions has an effect on the joints, so researchers have studied the phenomena caused by different temperature conditions. Zheng et al [1] observed the behavior of single-lap joints (SLJs) at temperatures of 50 °C and 80 °C under different loads. Pang et al [37] studied the influence of freeze-thaw cycles.…”

“…In an adhesive bonded joint, if the adherend materials are different (i.e., a FRP and a metal), the joint is considered dissimilar. For the rehabilitation of metal or FRP structures, adhesive bonding has considerable advantages over traditional connections, such as those by welding and bolts [1]. Adhesive bonding avoids stress concentrators caused by holes [5] and obtain a lighter joint that is more resistant to corrosion, with better load distribution and fatigue resistance [5,12,17].…”

Fiber-reinforced polymers (FRPs) combine characteristics of polymers and fibers to obtain a material with high mechanical strength and stiffness together with low specific mass and good corrosion resistance. The use of FRPs is growing as an alternative to metals in the automotive, aerospace and civil construction industries. Since adhesive bonded joints are an excellent way of joining materials due to the better load distribution, the use of FRPs for this purpose has been the objective of many studies about durability and structural safety. In service, environmental factors, including temperature, humidity, UV exposure and salt spray, can degrade materials, leading to unexpected failures. Since joints in service are subject to these multiple and uncontrolled adverse conditions, FRP adhesive bonded joint degradation has been studied by experiments that simulate these adverse environmental conditions. The combined analysis of the effect of environmental factors on the joint and the materials of each component allows predicting the system performance. In addition, optimal design parameters, such as the thickness of the adhesive, overlap length, materials and manufacturing processes, may be different according to the target application of the joint. Therefore, the achievement of optimal design parameters depends on the understanding of joint behavior in service. Based on analysis of the contribution of researchers in the specialized literature on adhesive joints and FRPs, this article reviews the main findings on degradation of adhesive joints and their components. Research topics for optimization of adhesive joint systems are also discussed.

Using adhesively bonded joints is an effective strategy for achieving lightweight designs. However, understanding the long‐term performance of these bonded joints remains a critical concern. Creep is a time‐dependent phenomenon induced by sustained mechanical loads, which can lead to viscous strain in adhesive materials. This strain has the potential to cause cracking in bonded structures over time. This study aims to investigate the creep and post‐creep behaviors of adhesively bonded aluminum joints, focusing on two crucial parameters: creep load level and creep duration. Butt adhesive joint (BAJ) specimens were fabricated and exposed to varying creep loads and times. Subsequently, quasi‐static tensile tests were conducted to assess the residual mechanical properties. The results indicated that higher creep loads resulted in increased creep deformations at constant creep durations. Furthermore, a downward trend was observed in the residual tensile mechanical properties of BAJ specimens following creep. Specifically, higher creep load levels and longer times led to more pronounced reductions in joint strength, strain, and stiffness. These reductions in joint mechanical properties were corroborated through joint fracture surface analysis. Additionally, mathematical models were developed using response surface methodology (RSM) to predict the experimental joint residual mechanical properties under different creep loads and times.Highlights Investigation of creep and post‐creep behaviors in adhesive joints. Higher creep load levels result in greater joint permanent deformations. Impact of higher creep load levels and durations on joint failure strength. Decreasing in the joint deformability and stiffness after creep.
