The intrinsic variability of coal gangue properties, however, necessitates exhaustive empirical investigations to elucidate its optimal mix proportion, a process often characterized by its inefficiency and associated costs. Addressing this limitation, the present study delineates a novel design methodology underpinned by data augmentation techniques and machine learning (ML) algorithms. Utilizing the capabilities of Variational Autoencoders (VAE) and Generative Adversarial Networks (GAN), we succeeded in augmenting the constrained experimental dataset. The reliability of such augmented data was subsequently evaluated through a custom difference matrix. Leveraging the expanded data, a quintet of ML models were devised and subjected to a secondary assessment. Through an amalgamation of the superior performing GAN and Multi-Layer Perceptron (MLP), we engineered a robust design framework, facilitating the creation of a mix proportion repository for AAMs derived from coal gangue. This framework, boasting a coefficient of determination (<i>R</i><sup>2</sup>) valued at 0.959 and an MAE of 2.643 MPa, offers pivotal insights for deriving mix proportions congruent with stipulated strength criteria. This endeavor signifies a notable stride in the realm of AAMs, underscoring the instrumental role of data augmentation and ML in refining mixture design paradigms.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822023","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 technique has become vital for enhancing productivity, flexibility, and quality in various sectors, including aerospace, automotive, and medical device manufacturing. This paper offers an extensive review of historical and recent developments in water jet generation techniques, focusing on continuous water jet (CWJ) and modulated water jet (MWJ) techniques. The review examines the erosion phenomena during jet–material interaction for both CWJ and MWJ, comparing their disintegration capabilities. MWJ techniques are further explored, including external pulsation methods using slotted discs, vibrating velocity transformers, ultrasonically excited jets, and internal pulsation with self-resonating water jets. The recent advances in self-resonating nozzle designs have improved MWJ efficiency by optimizing the energy and focus of the pulsed jet, thereby enhancing cutting precision and operational efficiency. However, the widespread adoption of these techniques is hindered by limitations in nozzle design and an unclear understanding of the mechanisms behind self-resonating water jets, due to the absence of a standard numerical model that accurately represents flow characteristics, pressure distribution, and velocity profiles. In this context, the current review also highlights the application of computational fluid dynamics analysis to develop high-efficiency nozzles, thereby advancing WJM systems to meet diverse industrial needs. This review seeks to understand MWJ experimentally and pinpoint numerical parameters required for an optimal modeling setup. Achieving this will aid in comprehending complex interactions under various environmental conditions, thus promoting structural optimization and practical industrial applications.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793122","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}

There is a lot of studies about the mechanical properties of ultra-high-performance concrete (UHPC) under impact loads. Among them, the dynamic increase factor (DIF, the ratio of dynamic property to quasi-static property) is one of the most important factors for evaluating the dynamic mechanical properties of concrete. This paper presents a systematic review of the mechanical properties of UHPC under compression at strain rates from 0.0003 to 300 s<sup>−1</sup>. Besides, mechanical properties of UHPC under tension are also reviewed at strain rates from 0.00033 to 150 s<sup>−1</sup>. Furthermore, the mechanisms of the strain-rate effects on UHPC are studied. The analysis results show that the strain-rate sensitive for strength of UHPC is lower than that of ordinary Portland cement concrete, resulting in the conventional DIF models of ordinary concrete are not suitable for UHPC. Therefore, the transition strain rates between high and low strain rates for compressive and tensile strength are determined separately. After that, two new DIF models of UHPC for compression and tension are established based on the existing studies with high precision, respectively. The difference of strain-rate between compression and tension is discussed. Besides, the strain rate effects of other properties under compression and tension including failure modes, strength, stress–strain curve, peak strain, and elastic modulus are discussed. This paper also proposes a research direction for future studies on UHPC under dynamic loads.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761755","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}

The 0.1 mm-thick pure Ti thin plates of different grain size were used in a mesoscopic uniaxial tensile experiment.

It was verified that the true stress increased during the plastic deformation, and the material elongation decreased as the grain size increased. The fracture mechanisms of the material gradually changed from ductile fracture to a mixture of ductile and brittle fracture, and then became brittle fracture. By analyzing the microstructural evolution, it was found that the frequency of deformation twins and the deformation coordination ability of grains decreased. The promotion of twinning on deformation was weakened with increasing the grain size. The flow strength was further increased to activate more slip systems to facilitate the deformation.

A power law function is employed to accurately characterize the distribution of FGP properties across the thickness of the face sheets. The micromechanical approach is adopted to derive the equivalent properties of the reinforced FGP layers, considering five distinct CNT distribution patterns as unique reinforcement strategies. The governing equations of the smart sandwich structure under the electric field impact are formulated based on first-order shear deformation theory (FSDT) by implementing Hamilton’s principle. Subsequently, the numerical results are obtained based on Navier’s technique for fully simply supported boundary conditions, utilizing a double-Fourier series. The reliability and efficacy of the suggested theoretical framework are validated through a comparative analysis of the available results. Eventually, a comprehensive study is conducted to examine various influential parameters on the natural frequency and loss factor of the doubly curved smart sandwich structure. The findings highlight that increasing the volume fraction of CNTs and the intensity of the applied magnetic field significantly influence the static stability of the rheological sandwich plate.
