“…Imanaka et al [105] evaluated the influence of the thickness ratio of the dissimilar double cantilever beam with acrylic and epoxy adhesives on the fatigue crack growth rate. The ratio of the thickness of the lower adherend to the upper adherend is a vital factor in determining the mode ratio 𝐺𝐺 𝐼𝐼𝐼𝐼 /𝐺𝐺 𝐼𝐼 (where 𝐺𝐺 𝐼𝐼 and 𝐺𝐺 𝐼𝐼𝐼𝐼 are strain energy release rate in mode I and II, respectively) and the stress distribution at the crack-tip.…”

This paper reviews the reported literature on dissimilar (non-matched adherend) adhesively bonded joints (ABJs), currently used bonding processes, and the mechanisms by which these types of joints fail when subjected to structural loading and environmental conditions. Additionally, approaches to improve the performance of dissimilar ABJs, through geometrical and material modifications, are also discussed. Many studies have reported on the strength and failure behaviours of adhesively bonded joints, but of those, few have reported on the performance of dissimilar ABJs. Unlike matched ABJs, the absence of accepted design approaches for dissimilar ABJs arises from their inherent inhomogeneity, which introduces complexities in load transfer mechanisms, in the distribution of stresses through the joint, and in the mechanisms by which the joint ultimately fails. Several authors have proposed approaches to improve the performance of adhesively bonded joints, variously through geometrical or material modification means, but there remains unmet research needs to better understand novel dissimilar ABJ designs.

“…Because large structures are always subject to periodic loads, fatigue performance of structural acrylic adhesives is important. Therefore, the effects of substrate thickness, 34 substrate materials, 35 adhesive thickness, 36 mode mixity, 37 and R-ratio 36,38 on the FCG behavior have been discussed for structural acrylic adhesives. However, research on this topic is scarce compared to epoxy adhesives, and further understanding will significantly help in predicting the fatigue life of joints more accurately.…”

Conducting displacement-controlled fatigue double cantilever beam tests of a structural acrylic adhesive, two different slopes were observed in the fatigue crack growth (FCG) relationship of the FCG rate versus the strain energy release rate (SERR) parameters depending on the loading conditions. Because fatigue is a two-parameter problem where stress waveforms contain cyclic and monotonic terms, the contribution of each term toward FCG needs to be clarified. Therefore, each slope was explained using SERR with load range and mean load. In addition, cases were observed where the slope changed with an increasing number of cycles. Accordingly, the FCG rate changes. Understanding the phenomenon is important to estimate the crack position from an engineering point of view. Therefore, FCG was categorized into three types using amplitude and mean displacement. After a sufficient number of fatigue cycles, amplitude played a more dominant role than R-ratio or mean displacement to determine crack location.
