Abstract ：
Lattice structures have attracted significant scholarly attention due to their exceptional mechanical properties, including lightweight characteristics and high strength. Their multifunctionality, such as energy absorption and vibration reduction, adds to their versatility. While extensive research has been conducted on the vibration reduction performance of plate-type, shell-type, and truss-type lattice structures, studies on cylindrical lattice structures are comparatively limited. To achieve broadband vibration suppression in cylindrical structures, this study proposes a novel cylindrical structure based on pyramid cells. The vibration suppression performance and the bandgap formation mechanism of the pyramid cylindrical lattice skeleton structure are examined, with a quantitative analysis of the influence of structural parameters on vibration suppression performance using normalized indicators. Results indicate that the structure demonstrates multiple bandgaps within the 0-1500 Hz range, exhibiting substantial vibration attenuation capabilities. Additionally, adjusting parameters enables the bandgap to shift toward lower frequencies. Finally, the experimental verification of finite element model has been performed by comparing the vibration transmission curves with a maximum relative error of -7.48% at the resonance peak. This work offers valuable insights for the application of cylindrical lattice structures in vibration and noise control fields.

Abstract ：
This study presents a new surface strengthening technique (cold upsetting manufacturing process) for engine valve seating face (VSF). The properties of the Ni30 superalloy VSF were characterized before and after cold upsetting. Compared to the solution-aging treatment (SAT) valve, the solution-cold upsetting-aging treatment (SCUAT) valve hardness was increased by 60 HV0.2. SCUAT valves exhibited higher internal dislocation degrees and local misorientation than SAT valves. Bench-top wear tests at 650 degrees C and 750 degrees C were conducted. The valve wear loss at 650 degrees C was higher than that at 750 degrees C. SCUAT valves show better wear resistance, with a total wear loss reduction up to 26.76 %. The SCUAT valve-seat insert contact pair wear mechanisms are adhesive and fatigue wear.

Abstract ：
Metallic sandwich panels featuring cellular metal cores are widely utilized across various sectors due to their exceptional load-bearing efficiency and design versatility. However, their application is often limited by the challenge of shaping complex geometries. This study introduces a novel thin sandwich panel incorporating stainless steel wire mesh (SSWM) core, designed to offer both lightweight properties and enhanced flexibility. Mechanical properties and forming limit diagrams of the sandwich sheet are assessed through tensile tests and Nakajima forming tests. The study investigates how the SSWM stacking angle and strain paths influence the panel's failure behavior and formability. Comparative analyses with monolithic stainless steel sheets of identical dimensions are also conducted. The findings reveal that the sandwich sheet exhibits comparable formability to the monolithic sheet in the tension-compression stain zone, with about 32% higher average specific tensile strength compared to the monolithic counterpart. Importantly, the formability and failure characteristics of the sandwich panel are significantly influenced by in-plane shear deformation of the SSWM core, which is primarily dictated by the SSWM stacking angle and strain paths. Notably, the sandwich sheet with 45 degrees stacking angle demonstrates superior plasticity and formability.

Abstract ：
This study addresses the enhancement of thermal stability of zinc alloys, which commonly experience reduced mechanical performance beyond 100 degrees C. The 304 stainless steel wires (SSWs) were utilized to fabricate a 3D porous metal rubber (MR) skeleton, facilitating the infusion of molten zinc alloys (ZA8) via squeeze casting to prepare MR/ZA8 composites. The impact of varying SSW volume fractions on the static compression creep (SCC) behavior of the MR/ZA8 composites at 250 degrees C was investigated, while exploring their SCC failure mechanisms. Energy dispersive spectrometer was used to analyze the MR/ZA8 composites both before and after the creep experiments. Findings revealed that in comparison to ZA8, MR/ZA8 composites exhibited notably lower SCC strain, diminishing with the increased SSW volume fraction. Under the applied stresses of 12 MPa, 17 MPa and 20.4 MPa, the steady-state SCC rate of MR/ZA8 composites experienced a reduction of 1 order of magnitude compared to ZA8. The apparent stress exponent n value ranged from 3.37 to 4.84, indicating a SCC mechanism dominated by dislocation climb within the two materials. The elemental composition of the MR/ZA8 composites remained largely unchanged, and the MR skeleton in the MR/ZA8 did not undergo oxidation.

Abstract ：
Satellites experience complex vibrational environments during their launch and operation, potentially leading to structural failures and equipment damage. This work aimed to mitigate this issue by designing a variable cross-sectional metal rubber isolator (VCMRI), which was fully constructed from metal and featured a symmetric structure. Initially, a finite element model of the VCMRI was developed, incorporating symmetric boundary conditions and employing the Bergstr & ouml;m-Boyce model to define variable cross-sectional metal rubber (VCMR) parameters. Subsequently, sinusoidal sweep tests were performed to investigate how variations in VCMR density, spring stiffness, and exc itation deflection angle affect the peak acceleration response and natural frequency of the VCMRI. Finally, simulation analyses were conducted and insertion loss was derived from the results to assess the vibration isolation performance of the VCMRI. The results indicate that the finite element model accurately captures the dynamic behavior of the VCMRI with minimal error. In addition, the VCMRI demonstrates robust vibration isolation performance by effectively integrating the influences of VCMR density, spring stiffness, and excitation angle, achieving insertion losses of up to 19.2 dB across a wide frequency range. It provides robust theoretical support for the design and performance optimization of isolation systems, with potential positive impacts on relevant engineering applications.

Abstract ：
Acoustic metastructures (AMs) are a type of artificial engineering materials composed of various micro-meso structure subwavelength units. They can exhibit distinct and exotic performances such as low mass, low volume, low frequency, and broadband through appropriate structural designs, which provide novel means for the exploration of physical interpretation in terms of individual case. Thus, the design strategies of AMs for unprecedented properties are of growing interest and attention. Beginning with the recent advances in structural design, a comprehensive review of the physical mechanisms and structural characteristics of four typical AMs, i.e., Helmholtz resonators, membrane-type AMs, coiling-up space structures, and lattice structures, is performed. Meanwhile, various engineering application potentials associated with regard to performance evolutions including sound absorption and noise reduction, acoustic cloaking, and acoustic lenses are introduced, as well as the corresponding design optimization strategies. Finally, the current scientific and technical challenges and the developmental trends of AMs are summarized. This review work aims to provide a design roadmap for next-generation AMs and a trigger on unsuspected physical mechanisms.

Abstract ：
Debonding at the wire/matrix interface is a critical failure mode for spiral skeleton-polyurethane composites. In this work, the interfacial damage characteristics were determined using a finite element model based on the cohesive contact approach. The cohesive surface quadratic stress criterion (CSQUADSCRT) and cohesive surface damage (CSDMG) were used to characterize the damage state of the interface. The results indicate that the stress shifts along the loaded direction during interface damage. As the matrix thickness and embedded depth increased, the pull-out load increased, whereas the failure displacement decreased. Using the base contact mode results in a significantly smaller damage displacement compared to the case without base contact. When the strain of the spiral wire composite is 0.4, no damage occurs at the composite interface. The stress and interface secondary tension damage factor of the spiral wire surface fluctuate, with damage at the loaded end face being significantly higher than at the vertically loaded end face. © 2024 Elsevier Ltd

Abstract ：
As a high-temperature resistant damping material, reducing vibration by coating with M-shape metal rubber (MMR) in a pipeline system is a promising solution due to its energy dissipation induced by micro dry friction between metallic wires. The main challenge for dynamic calculation and performance evaluation of elastic-porous metal rubber (MR) is derived from the intricate spatial network structure. In this work, the dynamic properties including acceleration admittance and insertion loss of the MMR-coated pipeline system were conducted by numerical simulation and experimental analysis. The constitutive models used to characterize hysteresis phenomena, including Yeoh and Bergström-Boyce models, were identified with different density parameters and adopted for steady-state dynamic numerical analysis. The sine sweep frequency test was conducted to verify the accuracy of the developed numerical model. The results indicate that the maximum error of stress-strain curve between numerical prediction and experimental measurement is 10.7%. In the frequency range of 0-1 500 Hz, the insertion loss of the MMR-coated pipeline system is positively correlated with the density of MMR, as opposed to the coating distance of pipeline clamps and the influence of excitation force is minimal. Furthermore, the error of dynamic response of the pipeline system in low frequency between the experiment and simulation is 4.7%, indicating that the accuracy of the hysteresis model in predicting the dynamic characteristic of MR materials is effective. © 2025 World Scientific Publishing Company.

Abstract ：
As a flexible component in high-pressure vessels and pipeline systems, bellows experience significant fluid-structure interaction effects under high-speed internal fluids and external vibrations. Nevertheless, their dynamic response mechanisms coupled with fluid-structure interaction mentioned below have not yet been clarified so far. In this work, a novel pressure-balanced metal bellow (PBMB) for low-stiffness and high-pressure resistance is firstly proposed. Several fluid-structure interaction models were considered to study the dynamic response characteristics of the PBMB. An experimental platform associated with fluid-structure interaction was established to validate the effectiveness of its vibration attenuation performance. The results indicate that the PBMB has an obvious vibration attenuation effect in the range of 5-90 Hz, and super-harmonic and sub-harmonic resonance phenomena occur in the range of 90-200 Hz. Under constant fluid conditions, fluid density, viscosity, flow velocity, and pressure are positively correlated with the response amplitude of the PBMB. The response of the PBMB oscillates at the fluid entry point due to both pulsating flow velocity and pulsating pressure. After several cycles, the response caused by pulsating flow velocity gradually decays and stabilizes. Thus, the impact of pulsating frequency on the stability of the response of bellows is insignificant during the initial cycles. © 2025 World Scientific Publishing Company.
