Existing methods often fail to accurately describe the preload relaxation mechanism under long-term storage conditions, where structural properties and material degradation interact. To address this issue, an accelerated degradation model has been developed to predict the preload relaxation behavior of composite bolted connections. This model considers the variable stress conditions during the relaxation process and the deformation coordination relationship within the structure. By combining accelerated experimental data with optimization algorithms, we can identify acceleration factors, ensure mechanism consistency, and determine model parameters. The model effectively describes the time-varying behavior of preload relaxation under the viscoelastic deformation of composite materials and the accelerated relaxation effects corresponding to different temperatures. It has clear physical significance, reflecting how material and structural parameters influence preload relaxation. Compared with the phenomenon of increasing prediction error over time in other models, the error of the proposed model remained stable within 0.5 % within 500 h, providing a theoretical basis for designing the durability of connections and for conducting accelerated tests.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"363 ","pages":"Article 119070"},"PeriodicalIF":6.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Curved variable stiffness beams transcend the limits of conventional composites offering new anisotropic coupling possibilities to tailor beam behaviour. However, the structural complexities introduced by variable stiffness effects in curved beams require computational tools that can capture non-classical responses characterising their behaviour. To address this problem, a numerical approach, rooted in indirect approximation techniques, is used to analyse the dynamic response of curved variable stiffness composite beams. By leveraging the merits of the emerging inverse differential quadrature method (iDQM), the study derives a new structural formulation for enhanced computational dynamic analysis of curved variable stiffness composite beams. The vibrational response of curved variable stiffness beams is governed by the interplay between geometric- and material-induced couplings due to curvature and point-by-point varying material distributions. Such interplay can be employed for design customisation, allowing for strategic adjustments in both geometry and materials to optimise performance. From the computational perspective, iDQM achieves over 90% reduction in degrees of freedom compared to one-dimensional and three-dimensional finite element method. Additionally, the variability in stiffness coefficients of variable stiffness composites introduces additional internal force terms, modifying the equilibrium equations in ways not observed in constant stiffness laminates. This feature creates opportunities to optimise material distribution and geometry by varying the stiffness along the beam’s length through variable fibre angle orientation and adjusting curvature to enhance dynamic performance over traditional constant stiffness beams.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"363 ","pages":"Article 119087"},"PeriodicalIF":6.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the influence of delamination, it is desired to investigate the influencing mechanism of delamination on the mechanical performance of the composite laminates. To this end, 14 types of glass fiber-reinforced polymers (GFRP) unidirectional composite plates with or without circular delamination are fabricated, in which the delaminations are designed in different diameters and locations along the thickness. Subsequently, the static three-point bending tests are performed, in which the test techniques including high-speed camera, digital image correlation (DIC), scanning electron microscope (SEM), and metallographic microscope are employed to measure the damage behaviors. When delamination is close to the upper surface, the experiments show that the layers between the delamination and the upper surface will occur local buckling with the increase of the delamination scale. Local buckling will accelerate delamination growth, whereas such an issue is scarcely reported in the published literature. In addition, the fiber bridging phenomenon can also be observed, which should be considered in the numerical analysis. Compared to the intact specimen, the bending strengths of the specimens with delamination at the location close to the upper surface are reduced by between 12.22% and 30.46%, while those of the specimens with delamination at the location close to the bottom surface are reduced by between 4.56% and 17.08%. To explore more influences of delamination on bending behaviors, an artificial neural network model (ANNM) has been constructed, which can quickly and accurately predict the bending strength of such structures. Such a method will be employed to investigate the bending strength degradation with different delamination sizes.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"362 ","pages":"Article 119068"},"PeriodicalIF":6.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
