Cork-STF structures have also been developed, mainly based on cork-layered structures interfacially reinforced with STF. The STF interface improves impact mitigation, but usually marginally. This work explores the effect of 3D STF reinforcements in cork-based hybrid composites for enhanced impact mitigation. The composite structures consist of adhesively bound cork composite layers containing an STF reinforcement. The variables were the STF reinforcement’s depth, area, and shape (circular and hexagonal). The samples were subjected to 10 J impacts. The impact force reduction obtained with the 3D STF structures was significant. This was verified even for 2 mm-thick STF reinforcements, achieving an average reduction of 20.3% compared to neat cork. The 30 mm cylindrical reinforcement with a 5 mm depth achieved the highest impact force reduction of 59.7%. The hexagonal-shaped reinforcement with a 16.5 mm side length achieved a 57.5% impact force reduction for the same area. Another finding was the 25% optimum ratio between reinforcement depth and sample thickness. Although higher ratios imply higher STF volume, the optimum threshold was 25%. Overall, 3D STF reinforcement in composite structures demonstrates excellent potential for protective structures.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01166-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this limitation, this study employs fractional derivative equations within the frameworks of three-component Zener and Boltzmann models to simulate the viscoelastic response of polymeric substances. Two distinct numerical methods are utilized to identify and estimate the parameters of these fractional derivative models. In the first method, model parameters are derived by fitting experimental data to hysteresis loops and their corresponding equations. The second method leverages time-series data, applying the least squares technique to determine the models' parameters and coefficients. Additionally, a data-fitting approach is employed to align the proposed mathematical models with experimental results from nanoindentation tests, ensuring their validation and accuracy. Key outcomes include the extraction of storage and loss moduli: the storage modulus consistently increased with rising dimensionless frequency across all fractional derivative orders. In contrast, the loss modulus initially increased to a dimensionless frequency of one before exhibiting a decreasing trend. Hysteresis loops, representing the energy dissipated per unit volume of material, revealed a reduction in damping with lower fractional derivative orders. Moreover, both methods demonstrated a small relative error when subjected to noise, indicating their robustness and high accuracy in estimating viscoelastic parameters from laboratory data within a narrow range of excitation frequencies.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional linear models fail to describe the non-linear accelerated creep properties of rocks and cannot characterize the influence of initial damage on creep properties. Considering this, creep tests were conducted on sandstone with different degrees of initial damage. In addition, a time-dependent damage model of rocks considering the effect of initial damage was established in conjunction with the improved Burgers model, Cowper–Symonds (CS) model, and theory of damage mechanics. The results indicate that creep stress affects the creep strain, and it determines the extent of the influence of initial damage on the creep strain in sandstone. The initial damage significantly influences the accelerated creep stage, and the creep failure stress linearly reduces and the time-dependent creep deformation time shortens with the rising degree of initial damage. The influence of initial damage on creep failure of samples is weakened with increasing confining pressure. The proposed time-dependent damage model of rocks considering the effect of initial damage overcomes the deficiency of traditional linear models in characterizing influences of accelerated creep and initial damage on creep properties. Based on the differential form of the time-dependent damage model, the secondary development of the time-dependent damage model is realized through the user-defined window of ANSYS/LS-DYNA, and the validity and correctness of the model are verified based on the experimental results and numerical examples. The research results provide theoretical guidance and reference for the study of creep mechanical properties and creep damage models, and also provide an important tool for the long-term stability prediction of caverns in practical engineering, which has significant engineering value and application potential.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technology involves deforming the aluminum sheet to create a mechanical interlock with the copper sheet, eliminating the need for additional elements, heat, or welding. First, the materials are characterized, and the most suitable strain hardening law is determined to model their post-necking behavior. Then, to model their ductile fracture behavior, the Modified Mohr–Coulomb (MMC) fracture criterion is calibrated through uniaxial tension, plane strain, and shear tension tests. Next, hole-hemmed joints are manufactured and subjected to shear tests. A comprehensive numerical model of the hole hemming process and shear test is developed to investigate the joints’ failure mechanisms and study the influence of mechanical interlock and process deformation history on joint performance. The findings show that the created joints achieve a maximum load of 3.56 kN and a displacement of 9.30 mm. The main failure mode predicted is hole bearing, which aligns with the mode observed in experimental tests. Finite element analysis reveals that while no damage occurs in the copper sheet during the joining process, this sheet is damaged during the shear test, leading to joint failure. Additionally, a higher mechanical interlock leads to greater failure displacement and load, although it decreases the initial load level. This research demonstrates that novel hole-hemmed joints can effectively connect aluminum and copper sheets, presenting promising results for battery applications.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01163-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a significant knowledge gap exists regarding a comprehensive analysis of their thermal insulation and sound absorption properties. This review seeks to bridge that gap by examining the effects of various waste materials, such as rubber, plastic, glass, ceramic, wood, construction waste, and bio-waste, on these properties in concrete. Incorporating these waste materials improves thermal insulation and sound absorption mainly by increasing porosity and creating interconnected micro and macro pores, leveraging the waste materials’ inherent high porosity and low density. Key findings from the review include a 77% reduction in thermal conductivity with 45% volume replacement of dry materials with plastic compared to control concrete. In addition, maximum sound absorption of 60% at 2000 Hz was achieved with a combination of fly ash and rubber at 30% weight replacement of coarse aggregate. Optimizing the thermal insulation and sound absorption properties of concrete is critically dependent on effective particle size, as it directly influences the concrete’s pore structure. Finer rubber particles (0.1–4 mm) significantly enhance thermal insulation by reducing thermal conductivity to 0.28 W/mK, compared to 0.44 W/mK for coarser particles (5–10 mm). In contrast, coarser particles improve sound absorption, achieving a peak absorption of 32% at 1000 Hz, compared to 27% for finer particles. This dual optimization strategy demonstrates the potential for tailored particle sizes to improve the necessary properties of concrete. The review also outlines future research directions and practical applications, highlighting the potential of recyclable waste materials in the building construction and insulation industry.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01160-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
