To this aim, a recent SMD modelling proposal based on uncoupled single-body measures (SMD-0, in the following) is specifically used for the calibration of key input parameters. Finite element numerical assumptions and findings are robustly supported by original experimental tests carried out on a case-study footbridge in Poland, proving that the proposed approach can serve as an effective tool for analysing vibrations in pedestrian systems. The research study, most importantly, integrates theoretical modelling with empirical and experimental validations, to enhance the credibility of the obtained results, as well as to support the general applicability of the presented methodology. Complex in-field tests are in fact conducted on the selected footbridge, aiming to assess the effects of pedestrians on its dynamic response. Numerical analyses, which are successively performed in ABAQUS/Standard, for a set of examined walking configurations, confirm the high sensitivity of the footbridge to resonance, which was also observed during the in-field tests. The presently used SMD-0 approach is further assessed towards past SMD literature proposals. As shown, the comparison of standard structural performance indicators (such as the peak acceleration value, root mean square and CREST factor) reveals a significant sensitivity of the footbridge response to the input parameters for the analyzed SMD models. Besides, the presently addressed SMD-0 model has the advantage of being based on single-body sensor measurements and its calibration is not affected by structural features. As such, potential applications of present findings could include the improvement of design standards and safety measures for similar structures.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01117-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388801","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}

The influence of dielectric fluids and cutting-edge electrode materials is highlighted for their significant role in enhancing machining performance and material removal efficiency. Various EDM techniques, including dry EDM, powder-mixed EDM, micro-EDM, and wire EDM, are explored with a particular focus on their effects on precision, surface quality, and overall material integrity. In particular, the machining of advanced ceramic composites, such as Si<sub>3</sub>N<sub>4</sub>–TiN and MoSi<sub>2</sub>–SiC, is emphasized, where optimizing process parameters becomes crucial to overcoming machining challenges. Key aspects like surface roughness, the formation of recast layers, and alterations in microstructure are scrutinized for their impact on the durability and properties of the final product. The review also sheds light on advanced optimization strategies, including Artificial Neural Networks (ANN), fuzzy Multi-Objective Optimization (MO), genetic algorithms, and hybrid methods like Particle Swarm Optimization (PSO) and Teaching–Learning-Based Optimization (TLBO). These tools are essential for boosting EDM performance, especially in applications demanding high precision.

For this purpose, the formation of the EFP (explosive formed penetrator) was analyzed for the classic scattered mine system with a double EFP-shaped charge. Then, after validating the numerical results against the experiment for the static tensile test, the authors performed a numerical analysis for a protective structure made of elastomer, placed between the mine and the bottom of the protected vehicle (parallel to the ground surface). Three variants of the thickness of the rubber element from 10 to 30 mm were analyzed in order to determine the impact of the shield thickness on the EFP formation process. In the final phase, the selected system was experimentally tested on a military training ground. The results obtained indicate that the use of analyzed shielding protecting bottom part of vehicles against mines and EFPs can significantly decrease the mine penetration capability. In addition, the use of the smoothed-particle hydrodynamic (SPH) method to describe the formation of the EFP projectile allowed to take into account the highly dynamic nature of the phenomenon. A novelty in the applied study is the use of an elastomeric cover in the immediate vicinity of the mine, which limits the EFP formation process and also limits the speed of the projectile. This is crucial because the key factor determining the penetrating capabilities of EFP is the high kinetic energy of the formed projectile. Based on the research conducted, areas of potential application of this type of covers can be distinguished. These will primarily be all types of heavy, armored vehicles moving in armed conflict zones, exposed to mines/IEDs/EFPs, such as armored infantry fighting vehicles and tanks.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01121-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361955","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}

The fracture mechanisms of the composites with different distributions of TiB were revealed by examining the fractography. The results showed that the composites with a homogeneous distribution of TiB exhibit brittleness at low temperatures, yet they demonstrate superior mechanical properties at high temperatures compared to those with network-distributed TiB. The small network structured composites have stronger grain refinement and higher TiB load-bearing efficiency and have better mechanical properties than the large network structured composites. At low temperature, the fractography shows that the network-distributed TiB can promote crack deflection and increase the fracture strain of the composites.

The Sommerfeld effect near the 1st-order resonance region is explored, and the minimum supplied power frequency threshold is found for the system to pass through the capture-jump behavior.
