The goal of this review paper is to compile the various research conducted in this field and offer insights into the S-N fatigue response of adhesive joints. This review delves into experimental studies that investigate different factors influencing the fatigue life of bonded structures, encompassing joint geometry, environmental conditions, and loading conditions. Subsequently, the various approaches to improve the fatigue performance and durability of bonded joints are explored. It also examines S-N based life prediction methods, analysing their merits and limitations in assessing the fatigue life of adhesive joints under different conditions. In addition, this review pays attention to studies that focus on real bonded joints. It highlights the importance of bridging the gap between simplified conditions and real-world performance to ensure the durability and safety of bonded joints under service conditions.</p><p>The review demonstrates that factors such as adhesive/adherend thickness, fillet, and overlap shape (e.g., wavy pattern, step, scarf) do impact fatigue life. However, the critical role played by overlap length in the fatigue life of bonded joints stands out. Improving fatigue life through adjustments, such as adhesive/adherend thickness, depends on the specific case. Therefore, further investigations are warranted in this area. The review suggests that carbon nanoparticles can enhance bonded joint fatigue strength. Hybrid reinforcement with carbon and organic nanoparticles, like silica, offers a cost-effective path to improve joint life. Regarding life prediction, there is currently no universal fatigue model that considers all parameters impacting the fatigue life of adhesive joints. Fatigue analysis methods considered for real adhesive joints vary between sectors. Initial designs frequently employ indirect fatigue life assessment methods, yet direct fatigue analysis through testing actual joints remains essential for ensuring reliability.</p></div>","PeriodicalId":34313,"journal":{"name":"Journal of Advanced Joining Processes","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666330923000407/pdfft?md5=27e90e4fe50e1ec7f6769f83da05d421&pid=1-s2.0-S2666330923000407-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138656116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functionally graded laminate composites have been used to overcome these drawbacks by varying the thickness of the raw laminate. The thickness changes in the user sheets were functionally 0.75 mm compared to the previous laminate. Finally, the initial sheets were transformed to three thicknesses: 3, 2.25, and 1.5 mm. The bond strength between the sheets was measured using the T-peel test. In the T-peel test, the initial crack length was 25 mm and the length of the weld zone was 111 mm. The results showed that the bond strength between the laminates improved with cooling after the CA-FSAM process. The bond strength is essentially determined by the amount of covalent bonding, which, in turn, is a function of the density on the treated surface.

A suitable and efficient process for joining structural components made of aluminium sheet metal is solid self-piercing riveting (SSPR). It eliminates the need for time-consuming preparatory work, such as the insertion of pilot holes, while making the joining process highly automatable.</p><p>Due to the process technology, the rivet itself first acts as a punching tool and then as a fastener to transfer the load of the joint. This leads to high requirements for the rivet in terms of strength and ductility.</p><p>In this paper, a new rivet design will be presented that focuses on adjusting the rivet geometry, as well as the material, to enable sufficient functionality in the installation and operational phase. Consequently, aluminium sheet metal can be joined in a wider range of applications using aluminium-based SSPR. With this newly developed aluminium rivet, it is possible to join the aluminium alloy EN AW-6111 PX, which is widely used in the automotive industry, up to a total sheet thickness of 3.1 mm for the first time. This development contributes to aluminium-based lightweight structures and ensures a good recyclability.</p></div>","PeriodicalId":34313,"journal":{"name":"Journal of Advanced Joining Processes","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666330923000237/pdfft?md5=e6203df3e494d1370d14a12466019e92&pid=1-s2.0-S2666330923000237-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72286605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
