Summary: A constitutive model for the dynamic shear modulus of magneto-sensitive elastomer is developed, considering temperature, prestrain, dynamic strain amplitude, and magnetic field dependence. Various functions and models are used to represent the dependencies, and after parameter identification, the model shows good agreement with experimental results, enabling accurate prediction of material performance under different conditions.

Summary: This study investigated the influence of the magnetic field during injection molding on the mechanical behavior of TPC filled with 85% SrFeO. Cuboid test samples were produced with and without a magnetic field, and mechanical tests were conducted along different directions. The results showed that the platelet-shaped particles exhibited certain orientation even without a magnetic field, and the mechanical properties were strongly influenced by the magnetic field. However, there seemed to be a limit where magnetic orientation led to mechanical disadvantages.

Summary: This study investigates the mechanical behavior of water-filled spherical shells when compressed onto a solid wall through experiments and numerical simulations. The results show that the presence of water significantly affects the deformation mechanism of the shells, and the internal water pressure variation can greatly improve their ability to withstand impacts.

Summary: This study prepared aligned aramid nanofiber/poly(vinyl alcohol) (ANF/PVA) nanocomposites with a nanofiller volume fraction of 48%, showing improvements in mechanical strength and stiffness due to effective stress transfer between aligned ANFs and PVA. The damping properties varied depending on different dissipation modes activated and loading angles relative to the nanofiber alignment direction, leading to viscoelastic properties exceeding conventional limits. Deepening the understanding of anisotropic dynamic mechanical responses is crucial for designing aligned nanocomposite materials for mechanical and electronic applications.

Summary: New composite materials based on carbonized elastomers were investigated as a bipolar plate material for all-vanadium redox flow battery, with enhanced mechanical properties and zero electrolyte permeability achieved through straight forming during synthesis. The influence of carbon fillers on electrical and mechanical properties of the composite was studied. The materials proved suitable for industrial vanadium flow batteries in the current densities range of 50-150 mA/cm(2).

Summary: Room temperature sorption kinetics was studied on semi-crystalline ethylene-co-butyl acrylate (EBA) polymer samples filled with carbon black (CB) in polar (ethanol) or non-polar (toluene) solvents. The equilibrium swelling data decreased with increasing CB content, as a result of increased crosslink density and tortuosity in the EBA/CB samples. The solvent preferential region was determined by analyzing the wetting coefficient, showing higher uptake and faster penetration for toluene compared to ethanol. The transport mechanisms were discussed using Peppas-Sahlin and Berens-Hopfenberg models, and a correlation between sorption data and mechanical response was observed. Additionally, the stress-strain curves of swollen and dry samples were analyzed using the Haward-Thackray model considering microstructure characteristics.

Summary: In this study, silicone rubber/Al@SiO2 composites with high dielectric constant, low dielectric loss, and high electrical breakdown strength were successfully developed by controlling the shell layer thickness and the content of the core-shell filler. The use of core-shell fillers increased the Maxwell-Wagner-Sillars relaxation process and reduced the dielectric loss in the composites. This strategy can inspire the preparation of other high dielectric constant composites.

Summary: This study investigated the effect of silicon nitride (Si3N4) as a thermally conductive filler on the mechanical, microstructural, and physical properties, as well as the kinetics of the curing reaction, of styrene-butadiene rubber/butadiene rubber (SBR/BR) composites. The results showed that the presence of Si3N4 improved the tensile, hardness, and compression properties of the composites. The enhancement in properties was observed with increasing filler loading, with the composite containing 6 phr Si3N4 exhibiting the most significant performance improvement.

Summary: Heterogeneous membranes are thin and soft structures with spatial variations in material property and thickness. Understanding the mechanical behavior of these materials requires accurate and efficient characterization methods. This paper introduces an inverse method based on machine learning for extracting mechanical properties from full-field strain distributions, showing comparable accuracy to traditional methods but significantly faster.

Summary: Roll-to-Roll manufacturing aims to scale ultraviolet- and thermally cured nanoimprint lithography to commercial production speeds and volumes. Winding is an important step in storing large quantities of nanoimprinted webs, but the contact pressure during winding can affect the imprinted peak heights and functionality of the surface. This study develops a numerical model to investigate the impact of contact pressure on the imprinted web during winding.
