The integration of magnetohydrodynamic (MHD) nanofluids within porous media has surfaced as an innovative strategy for augmenting heat transfer efficacy under intricate thermal scenarios. This investigation examines the synergistic impacts of magnetic field intensity, Ohmic heating, internal heat generation, thermal radiation, and variable permeability on the mixed convection flow of Cu–H₂O nanofluids over a buoyancy-driven vertically heated plate situated in a porous medium. The governing nonlinear boundary-layer equations are reformulated into a system of ordinary differential equations through similarity transformations and solved numerically utilizing the MATLAB BVP4C solver. The findings indicate that an increase in nanoparticle volume fraction, heat absorption, and magnetic parameter considerably diminishes the velocity field, whereas heat generation amplifies the temperature profile for both uniform permeability (UP) and variable permeability (VP) scenarios. An escalation in the buoyancy parameter (Gr/Re²) promotes fluid flow and decreases the thermal boundary layer thickness, thereby enhancing convective heat transfer. Elevated radiation and permeability parameters improve heat transport attributes, while stronger magnetic fields diminish velocity owing to the influence of the Lorentz force. The Nusselt number exhibits an upward trend with increasing Grashof number across all radiation parameters, signifying enhanced buoyancy-driven heat transfer. Under conditions of variable permeability, the velocity distribution ranks as Ag–water &lt; Cu–water &lt; CuO–water. These results underscore the critical influence of MHD phenomena, Ohmic heating, and the characteristics of porous media in regulating heat transfer efficiency and offer valuable perspectives for the development of sophisticated thermal management and energy systems.</p></div>","PeriodicalId":593,"journal":{"name":"International Journal of Mechanics and Materials in Design","volume":"22 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148751034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of nonlinear radiation, slip, and catalysis are also considered. The leading PDEs are transmuted into their non-dimensional forms and then tackled numerically. The impacts of the radiation, magnetic field, slip, viscous dissipation, and nanoparticle volume fraction on the flow and thermal dynamics are assessed. To show the reliability of the chosen numerical method, a comparison in a limiting case with available data in the literature is made, and an error estimation of less than 10⁻⁴ is achieved. The sensitivity analysis shows that the magnetic parameter lowers the Nusselt number by over 65%. The HT is raised approximately 48% by the radiation parameter. A moderate positive contribution of 32% is made by the slip parameter, whereas the smaller impacts of 21% and 12% are respectively made by the heat source/sink parameter and volume fraction of single-walled CNT. An elevated temperature within the thermal boundary layer (BL) is predicted by the Hamilton-Crosser (HC) model as compared to the Yamada–Ota (YO) model. From these findings, it is observed that the magnetic damping and radiative transport are of utmost importance for the HT mechanism. Also, the slip and customization of nanoparticles provide other means of controlling the HT.

The results indicate that increasing the helicoidal angle reduces structural strength and stiffness but promotes stress redistribution, delays local buckling, and significantly enhances energy absorption capacity.

The incorporation of rounded corners further improves the mechanical performance, with the HTR₁₀ configuration exhibiting maximum increases of 136%, 334%, and 333%, respectively.

These two factors together result in a significant discrepancy between the theoretically calculated magnification and experimental results. To address this issue, this paper proposes a precise mechanical modeling method based on the flexibility matrix. First, the flexibility matrix of flexure hinges considering the shear effect is derived using the Timoshenko beam theory.

The arc-star shape honeycomb-rodless (ASH-R) and the bidirectional re-entrant honeycomb-rodless (BRH-R) are constructed, providing ideal solutions for eliminating the imbalance of strength-mass ratio caused by insufficient relative density of traditional honeycomb structures. Through systematic finite element analysis (FEA), the mechanical behaviors of the two honeycombs are comprehensively evaluated. Based on the analysis data, the response surface modeling (RSM) is accurately constructed, which provides a reliable basis for the subsequent optimization. Combining the non-dominated sorting genetic algorithm-II (NSGA-II) and RSM, multi-objective optimization design is carried out for ASH-R and BRH-R to achieve multi-objective synergistic optimization, such as equivalent tensile modulus, bending modulus, mass and Poisson’s ratio. The equivalent tensile modulus and equivalent bending modulus of the ASH-R are increased by 710% and 123.2%, respectively, and the equivalent out-of-plane bending modulus of the BRH-R is increased by 852.7%, which significantly enhances the load-bearing capacity of the structure. Both structures also realize the lightweight design to a certain extent while guaranteeing the performance. The Poisson’s ratio of the structure is controlled within a very small range, which is close to the ideal zero Poisson’s ratio state ( − 0.0192). In addition, the in-plane tensile test, cantilever beam test and three-point bending test are used. It is found that the ASH-R has excellent deformation capability, and maintains the structural integrity when subjected to large deformation, while the BRH-R shows higher equivalent tensile modulus, and possesses stronger deformation resistance under the tensile load. The experimental and simulation errors are both less than 9.5%. The superior anti-deformation ability exhibited by the metamaterial also provides a design idea and theory for in-plane deformation and out-of-plane load-bearing of the new generation of morphing aircraft.

The principal novelty of this work lies in the unprecedented integration of Eringen’s nonlocal elasticity, memory-driven viscoelasticity, and MGT non-Fourier heat conduction within a spherical <b>coupled-field</b> configuration, an integration that captures the simultaneous effects of size-dependent stiffness, finite-speed thermal waves, and intrinsic material damping. The governing equations, which incorporate temperature-dependent thermal conductivity and transverse magnetic field effects, are solved analytically using Laplace and Kirchhoff transformations, yielding closed-form solutions in terms of modified spherical Bessel functions. Beyond resolving the paradox of infinite thermal propagation speed inherent in classical thermoelasticity, the present analysis reveals a novel coupled damping mechanism arising from the synergistic interaction between MGT thermal relaxation and spatial nonlocality. Quantitative parametric analyses demonstrate that this coupling profoundly attenuates the thermomechanical fields: increasing the nonlocal parameter from 0.00 to 0.16 induces a 41.7% reduction in peak radial stress, a 42.5% reduction in peak hoop stress, and a 36.4% contraction in thermal penetration depth. Fast viscoelastic relaxation further diminishes peak hoop stress by 27.1% and localizes thermal expansion near the heated boundary.
