Despite extensive research, the effects of GO sheet arrangement and oxidation profiles on the mechanical and viscoelastic properties of these nanocomposites remain underexplored, and the underlying deformation mechanisms have not been explicitly unveiled. In this study, we employ coarse-grained molecular dynamics simulations to investigate how distinct GO arrangements (separated vs. stacked sheets), varying interfacial interactions, and a range of oxidation profiles impact the mechanical and viscoelastic properties of GO-poly(methyl methacrylate) (PMMA) nanocomposites. Our findings reveal that GO sheet arrangement plays a crucial role in determining the mechanical properties of nanocomposites, with separated GO sheets typically resulting in higher elastic and shear moduli due to increased interfacial area and stronger nanoconfinement effects. Additionally, stronger interfacial interactions enhance these moduli, with oxidation degree playing a complex role by simultaneously weakening GO’s intrinsic stiffness. Under shear deformation, stacked GO cases exhibit inter-sheet sliding, driven by weaker GO inter-sheet interactions and stronger GO-PMMA adhesion. The inter-sheet sliding enhances the loss modulus and loss tangent of the GO-PMMA nanocomposites, with the sliding magnitude directly correlating with the dynamic moduli. Our results indicate that polymers reinforced with stacked GO sheets can achieve superior damping capability through the activation of GO inter-sheet sliding. This makes them particularly suitable for applications requiring enhanced energy dissipation. This study highlights the pivotal role of GO arrangement in shaping the mechanical and viscoelastic behavior of polymer nanocomposites, providing valuable insights for tailored nanocomposite design.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"297 ","pages":"Article 110351"},"PeriodicalIF":7.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its current application in limit analysis primarily relies on triangular meshes. Existing mesh refinement schemes are often not general enough to accommodate complex discretizations. To address this, the paper introduces a dissipation-based automatic remeshing strategy for finite element limit analysis, which supports meshes with arbitrary element shapes and enables interfacial velocity discontinuities and selective refinement. The element deformation is assumed to be homogeneous. The approach is applied to analyze the collapses of the weightless cohesive-frictional strip footing and of a masonry arch bridge interacting with the backfill. The results obtained both indicate the reliability and effectiveness of the proposed remeshing procedure, showing competitive efficiency when compared with a global uniform refinement. Applying remeshing to polygon discretizations is crucial since it can effectively release the locking effect induced by the constant-strain assumption inside the elements, and the converged load prediction can gain precision comparable to the triangular one. Polygon elements exhibit great efficiency in large-scale applications, requiring only 1/5 – 1/2 of processing time when compared with triangular meshes. Regular polygons are more recommended given the lower sensitivity to the initial mesh. The proposed procedure broadens the applicable scenarios of remeshing in limit analysis, providing also a paradigm for mesh refinement in other mesh-based simulations.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"297 ","pages":"Article 110349"},"PeriodicalIF":7.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SBG design comprises three essential phases: blank geometry, tooth surface geometry, and contact performance prediction. The lack of standardized frameworks makes the SBG design process heavily dependent on empirical expertise, limiting the full potential of SBG design. To address this limitation, an integrated design optimization method (IDOM) that integrates the blank geometry, tooth surface geometry, and contact performance was proposed. First, a general mathematical model for face-milled SBGs was established using tooth shrinkage principles and homogeneous coordinate transformations. Subsequently, a geometric optimization method for lightweight SBG blanks (GOMSB) was developed using genetic algorithms. Based on this, the spatial meshing theory and topological surface techniques were employed to construct a mathematical deviation model between the target and theoretical pinion tooth surfaces, leading to a high-performance geometric optimization method for SBG surfaces (GOMSS). An enhanced tooth contact analysis method integrating differential geometry and Hertz contact theory was proposed. This method quantifies time-varying loaded contact characteristics by combining elastic potential energy principles with meshing equilibrium conditions and establishing parametric criteria for iterative tooth surface modification. Finally, the IDOM was validated through SBG pair design case studies using numerical modeling, assembly, and meshing simulation analysis. Furthermore, the applicability of GOMSB and GOMSS as well as the key parameters influencing the fatigue strength and contact performance of SBG pairs and their operational laws were systematically analyzed, thereby establishing fundamental design principles for high-performance SBG development.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"296 ","pages":"Article 110348"},"PeriodicalIF":7.1,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike prior studies, the current numerical model integrates millimeter-scale gap flows (in crown gap and band gap) and a complete shaft system with realistic bearing constraints, enabling accurate simulation of complex fluid-structure interactions. A two-way FSI method was employed to accurately characterize the vibration and dynamic stress response of the shaft system, with a focus on pressure fluctuations, runner vibrations, and blade stresses. Study results reveal that pressure fluctuations in flow channels are primarily driven by runner rotation and the first type of rotor–stator interaction (RSI). High-frequency pressure fluctuations (13–24 times the runner rotational frequency) attribute to discontinuous vortices within the band gap. In contrast, runner structural responses are dominated by the second type of RSI, whose effects propagate through the flow system and significantly influence the radial forces exerted on the runner. These forces, intensified by millimeter-scale flows in the crown and band gaps, lead to runner imbalance and large-amplitude horizontal vibrations.

This study compares the behaviour of three nuclear graphite grades, fine-grained IG-110, coarse-grained NBG-18 and medium-grained PCEA, subjected to the uniaxial compression (UC) and the splitting tensile (ST) tests. It was found that the IG-110 graphite has a more favourable combination of ultimate strength and ductility when compared to the NBG-18 and PCEA grades containing large pores acting as strain concentrators. The formation of shear cracks was the primary failure mode under compression, while the formation of a main tension crack in the middle of the specimen was the primary failure mode during the ST test. The inelastic and fracture response was modelled using finite element simulations employing the concrete damaged plasticity (CDP) material model with the dilation angle parameter value selected by two different optimisation processes; a decoupled optimisation was run on the UC and ST models separately, and a coupled optimisation was performed on the UC and ST models running simultaneously. The best predictions were obtained when the value from the coupled optimisation was used. The results showed that the CDP model accurately describes the inelastic behaviour and peak force of all graphite grades and could also capture the failure modes observed experimentally in both UC and ST tests.

This study addresses this critical research gap by systematically investigating the influence of thermo-viscous effects on sound absorption in compact MPAs with parallel coiled-cavities of different depths. An analytical prediction model that effectively incorporates both micro-perforation and cavity thermo-viscous effects is developed to predict absorption coefficients. The model is validated through finite element simulations coupling pressure and thermo-viscous acoustic fields under normal and oblique incidence, as well as impedance tube experiments. Based on the analytical model, detailed parametric studies are conducted on the thermo-viscous effects on MPAs with six parallel coiled sub-cavities, with widths ranging from 16 mm to 1 mm. Normal, oblique, and random incidence conditions are considered for a comprehensive analysis. Results show that cavity thermo-viscous effects within the absorber structure significantly enhance absorption performance by: (1) smoothing valleys in the absorption coefficient spectra within the 500–4000 Hz range, (2) causing slight shifts in absorption peaks, and (3) modifying the pressure distributions within the cavity. The impact of sub-cavity width is particularly pronounced when the width approaches the thickness of thermal and viscous boundary layers attached to cavity walls, revealing the critical role of thermo-viscous boundary layer matching in optimizing absorption performance. Case studies demonstrate that optimizing the sub-cavity width to 1 mm leads to remarkable improvements in average absorption coefficients by 5.4%, 9.8%, and 12.4% over the 260–4000 Hz range under normal, oblique, and random incidence conditions, respectively, achieving approximately 0.9, thereby enabling ultra-thin wideband high-performance absorption structures.
