Silicon carbide particle reinforced aluminium matrix composites (SiCp/Al) are widely used in corrosive service environments, where corrosion-induced damage can severely compromise their mechanical integrity. Despite existing studies on corrosion behaviour and mechanical properties, the quantitative coupling between corrosion damage morphology and the resulting mechanical degradation of SiCp/Al composites has not yet been systematically clarified. In this study, such a link is established through a combined experimental and numerical framework. Both general (uniform) and localised corrosion were characterised following 96 h of immersion in EXCO solution. The results reveal a quantitatively resolved trend: the depth of general corrosion remains nearly independent of SiCp volume fraction, while the severity of localised corrosion increases markedly with increasing SiCp content. Stress–strain responses for composites with four representative SiCp volume fractions ranging from 0% to 45% were obtained experimentally and reproduced numerically. The phase field AT1 model, coupled with a homogenisation method, effectively predicted the mechanical behaviour of SiCp-reinforced composites before and after corrosion across a wide range of SiCp volume fractions, extending beyond those directly tested experimentally. Additionally, ultimate strength and failure strain maps were constructed as functions of SiCp volume fractions and corrosion degrees, providing a quantitative design and assessment tool for evaluating the mechanical performance of SiCp-reinforced aluminium composites in corrosive environments.
碳化硅颗粒增强铝基复合材料(SiCp/Al)广泛应用于腐蚀性服务环境,在这些环境中,腐蚀引起的损伤会严重损害其机械完整性。尽管已有关于SiCp/Al复合材料腐蚀行为和力学性能的研究,但腐蚀损伤形态与由此产生的力学降解之间的定量耦合尚未得到系统的阐明。在本研究中,通过实验和数值相结合的框架来建立这种联系。在EXCO溶液中浸泡96小时后,对一般(均匀)和局部腐蚀进行了表征。结果显示了一个定量解析的趋势:总体腐蚀深度几乎与SiCp体积分数无关,而局部腐蚀的严重程度随着SiCp含量的增加而显著增加。实验得到了SiCp体积分数为0% ~ 45%的复合材料的应力应变响应,并进行了数值模拟。相场AT1模型与均质化方法相结合,有效地预测了SiCp增强复合材料在大范围SiCp体积分数腐蚀前后的力学行为,超出了直接实验测试的范围。此外,构建了SiCp体积分数和腐蚀程度的极限强度和破坏应变图,为评估SiCp增强铝复合材料在腐蚀环境中的力学性能提供了定量设计和评估工具。

To improve interfacial condition and mechanical properties of basalt/carbon fiber reinforced polymer (BCFRP) laminates, this study innovatively employed a double electrospinning technique to prepare multi-directional polyvinylidene fluoride (PVDF) fiber veils on carbon fiber (CF) fabric surfaces. Energy-dispersive X-ray spectrometer (EDS) confirmed the uniform distribution of fluorine, verifying the successful anchoring of PVDF onto the CF fabric. With systematically varied areal densities (0.1-0.5 g/m²), the PVDF veils demonstrated a substantial enhancement in mechanical performance, with the 0.4 g/m² density identified as optimal. This specific formulation yielded remarkable flexural and compressive strengths of 529.26 MPa and 248.08 MPa, corresponding to significant improvements of 37.9% and 43.6%, respectively, over the unreinforced specimen. Microstructural analysis via X-ray microscopy (XRM-CT) and scanning electron microscopy (SEM) revealed that the multi-directional PVDF veils established continuous fiber bridges at the interlaminar interface. These bridges provided a better fracture resistance to prevent the generation and propagation of micro-cracks, promoting failure mode variation from traditional dominated delamination to shear-dominated failure. This work established a novel technical pathway for developing high-performance PVDF@BCFRP laminates, presenting a viable alternative to traditional CFRP composites for civil applications.
为了改善玄武岩/碳纤维增强聚合物(BCFRP)复合材料的界面状况和力学性能,本研究创新性地采用双静电纺丝技术在碳纤维(CF)织物表面制备了多向聚偏氟乙烯(PVDF)纤维纱。能谱仪(EDS)证实了氟的均匀分布,验证了PVDF在CF织物上的成功锚定。在不同的面密度(0.1-0.5 g/m²)下,PVDF薄膜的机械性能得到了显著提高,其中0.4 g/m²的密度被认为是最佳的。该配方的抗折强度和抗压强度分别为529.26 MPa和248.08 MPa,较未加筋试件分别提高了37.9%和43.6%。通过x射线显微镜(xrd - ct)和扫描电镜(SEM)的微观结构分析表明,多向PVDF膜在层间界面处建立了连续的纤维桥。这些桥梁提供了更好的抗断裂能力,防止微裂纹的产生和扩展,促进了破坏模式从传统的以分层为主的破坏转变为剪切为主的破坏。这项工作为开发高性能PVDF@BCFRP层压板建立了新的技术途径,为民用应用提供了传统CFRP复合材料的可行替代方案。

Auxetic metamaterials have attracted significant interests due to their unusual mechanical properties. However, the influence of negative Poisson’s ratio on wave spin (local polarization) remains largely unexplored. Here, we demonstrate that Poisson’s ratio governs anomalous wave spin: in the low-frequency regime, the transverse spin of the longitudinal wave reverses from auxetic to non-auxetic metamaterial tubes, while the spin of the flexural wave changes minorly. Both waves, however, exhibit spin-momentum locking mechanism. The elastic spin is theoretically modeled using equivalent continuum tubes and is further verified through experiments and simulations on actual metamaterial tubes. Interestingly, under one single spin source excitation, we observe the simultaneous asymmetric routing of the two waves: they propagate in the same direction in auxetic tubes, but in opposite directions in non-auxetic tubes. This study provides fundamental insight into the anomalous spin in auxetic tubes. Our findings add on the toolkit for asymmetric wave routing and suggest a potential method for evaluating Poisson’s ratio.
增塑型超材料以其独特的力学性能引起了人们的广泛关注。然而,负泊松比对波自旋(局部极化)的影响在很大程度上仍未被探索。在这里,我们证明了泊松比控制着异常波自旋:在低频区,纵波的横向自旋从无氧超材料管向无氧超材料管反转,而弯曲波的自旋变化很小。然而,两种波都表现出自旋动量锁定机制。利用等效连续介质管对弹性自旋进行了理论模拟,并在实际超材料管上进行了实验和仿真验证。有趣的是,在单一自旋源激发下,我们观察到两个波的同时不对称路径:它们在消声管中沿同一方向传播,但在非消声管中沿相反方向传播。这一研究提供了对缺氧管中异常自旋的基本认识。我们的发现增加了不对称波路由的工具包,并提出了一种评估泊松比的潜在方法。

Cable-Driven Continuum Robots (CDCRs) have attracted significant attention due to their high dexterity and compliance. High-fidelity mechanical modeling plays a crucial role in the design optimization, mechanical analysis, and motion control of CDCRs. However, most existing models rely on simplified assumptions that neglect cable viscoelastic deformation, unilateral tension constraints, and frictional effects, and therefore fail to capture the intrinsic nonlinear mechanisms. This study proposes a unified smooth Differential Algebraic Equation (DAE)-based complementarity dynamic modeling framework that simultaneously couples cable viscoelasticity, unilateral slack, and friction within a single consistent formulation, going beyond prior complementarity-based models that consider only slack or only friction and that commonly assume linear-elastic cables. The proposed formulation significantly improves convergence robustness and computational efficiency. Numerical studies on representative CDCR configurations demonstrate stable and efficient simulation under strong nonlinear coupling and reproduce key behaviors observed in practice, including viscoelastic creep and stress relaxation, stick–slip hysteresis, path dependence, and stiffness discontinuities induced by cable slack. The proposed framework provides a reliable tool for high-fidelity analysis and performance improvement of CDCRs.
电缆驱动连续体机器人(CDCRs)由于其高灵活性和顺应性而引起了人们的广泛关注。高保真力学建模在cdcr的设计优化、力学分析和运动控制中起着至关重要的作用。然而,大多数现有模型依赖于简化的假设,忽略了索的粘弹性变形、单边张力约束和摩擦效应,因此无法捕捉内在的非线性机制。本研究提出了一个统一的基于微分代数方程(DAE)的互补动态建模框架,该框架在单一一致的公式中同时耦合电缆粘弹性、单边松弛和摩擦,超越了先前仅考虑松弛或摩擦的基于互补的模型,通常假设线弹性电缆。该方法显著提高了收敛鲁棒性和计算效率。对典型的CDCR结构的数值研究表明,在强非线性耦合下,CDCR结构的数值模拟是稳定有效的,并重现了实践中观察到的关键行为,包括粘弹性蠕变和应力松弛、粘滑滞后、路径依赖以及索松弛引起的刚度不连续。该框架为cdcr的高保真度分析和性能改进提供了可靠的工具。

Contemporary footbridges, due to their slender and lightweight structural characteristics, are prone to human-induced vibrations. This paper proposes a vibration mitigation strategy for lively footbridges under walking-induced excitations, which are modeled as moving harmonic loads, by employing nonlinear vibration absorbers. Firstly, a novel vertical polynomial stiffness nonlinear vibration absorber (VPNVA) incorporating a gravity compensation mechanism is proposed. Experiments on the stand-alone VPNVA indicate that the implementation scheme enables the effective realization of polynomial stiffness, with frequency responses of the VPNVA showing good agreement with theoretical predictions. Secondly, the response regimes of the system, consisting of two VPNVA devices installed on both sides at the midspan of a lively footbridge, are analyzed with consideration of multi-modal vibrations. The results show that the vibrations on both sides of the footbridge may evolve along the lower branch of the slow invariant manifold (SIM), both may jump from the lower branch to the upper branch, or, one side may remain along the lower branch while the other jumps to the upper branch when both bending and torsional mode vibrations are included. Finally, the VPNVA with optimal stiffness coefficients and a low damping coefficient demonstrates effective vibration suppression, and the performance is further improved with additional optimal damping. Under detuning conditions where both bending and torsional modes fall within the walking excitation frequency range, the optimally designed VPNVA still maintains satisfactory vibration suppression performance, indicating its effectiveness in controlling multi-modal vibrations, even with frequency detuning. Compared with the conventional TMD, the VPNVA exhibits lower sensitivity to stiffness variations under low damping conditions. The proposed VPNVA provides an effective approach to vibration control of large-scale structures under moving loads.
现代人行桥由于其细长和轻便的结构特点,容易受到人为振动。本文提出了一种基于非线性吸振器的人行桥在移动谐波荷载作用下的减振策略。首先,提出了一种包含重力补偿机制的垂直多项式刚度非线性吸振器(VPNVA)。在单机VPNVA上的实验表明,该实现方案能够有效实现多项式刚度,VPNVA的频率响应与理论预测吻合较好。其次,在考虑多模态振动的情况下,分析了由安装在人行桥跨中两侧的两个VPNVA装置组成的系统的响应形式。结果表明:考虑弯扭模态振动时,人行桥两侧的振动可能沿慢不变流形(SIM)的下支演化,也可能从下支跳到上支,或者一侧沿下支保持不变而另一侧跳到上支。最后,刚度系数最优且阻尼系数较低的VPNVA能够有效抑制振动,并且在附加最优阻尼的情况下,性能得到进一步改善。在弯曲模态和扭转模态均在行走激励频率范围内的失谐条件下,优化设计的VPNVA仍然保持了令人满意的抑振性能,说明即使在频率失谐的情况下,其对多模态振动的控制是有效的。与传统的TMD相比,VPNVA在低阻尼条件下对刚度变化的敏感性较低。该方法为大型结构在移动荷载作用下的振动控制提供了有效的方法。

High-throughput characterization (HTC) techniques grounded in contact mechanics have significantly propelled advancements in materials science by enabling quantitative assessments of material properties efficiently and precisely. Tailored for HTC of whole-field material properties, an effective Kolmogorov-Arnold Transformer neural operator (KATNO) architecture is established to conduct the inverse contact analysis, where the datasets are prepared through finite element analysis of isotropic inhomogeneous cubes as well as symplectic analysis of layered cylinders. The normalized cross-attention and self-attention modules are designed to evaluate queries, keys, and values within the Transformer framework. Additionally, a gating network is employed to average the weights of multiple expert group-rational Kolmogorov-Arnold networks (GR-KANs). In representative numerical examples, predicted results and ground truth exhibit high consistency. Various KATNO architectures are explored to identify essential design criteria according to the mean L2 relative error. The limitations of neural operators based on contact analysis are highlighted, offering insights for future advancements in HTC techniques.

A genus-tuning design on minimal surfaces for open-cell mechanical metamaterials 开孔机械超材料最小表面的属型调谐设计

Mechanical metamaterials based on triply periodic minimal surfaces (TPMS) offer unprecedented opportunities for tailoring mechanical properties through their mathematically defined open-cell architecture. Although existing studies have examined the intrinsic properties, multi-physical applications, and geometric designs of TPMS metamaterials, a systematic approach for broad mechanical tunability remains underdeveloped. Here, we introduce a genus-tuning strategy as a novel geometric degree of freedom for systematically designing TPMS-based mechanical metamaterials. Through integrated numerical and theoretical analyses, we demonstrate that increasing genus induces a structural evolution that changes the Gaussian curvature distribution while preserving zero mean curvature. The Gaussian curvature distribution on newly generated TPMS metamaterials plays a pivotal role in modulating the stress distribution, thereby enabling flexible tuning of stiffness and energy absorption across a wide range. Notably, the specific Young's moduli increased by up to 47% on average within a relative density range of 0.04–0.12, and reached 177% of the Hashin-Shtrikman upper bound for maximum values, while specific shear moduli improved by up to 84.0%. Directional genus-tuning enabled TPMS metamaterials to attain nearly 94% of the stiffness of honeycombs under uniaxial load. A pronounced increase in specific energy absorption is demonstrated by 3D printed TPMS metamaterials, rising from 1.77 J·g−1 to 6.93 J·g−1, as the genus level is increased. Overall, this work establishes genus as a fundamental topological descriptor for mechanical performance and provides a powerful design paradigm for developing lightweight, highly customizable metamaterials.
基于三周期最小表面(TPMS)的机械超材料通过其数学定义的开孔结构为定制机械性能提供了前所未有的机会。虽然现有的研究已经研究了TPMS超材料的内在性质、多物理应用和几何设计,但广泛的机械可调性的系统方法仍然不发达。在这里,我们引入了一种新的几何自由度策略,用于系统地设计基于tpms的机械超材料。通过综合的数值和理论分析,我们证明了增加格会引起结构演化,在保持平均曲率为零的情况下改变高斯曲率分布。新生成的TPMS超材料上的高斯曲率分布在调节应力分布方面起着关键作用,从而能够在大范围内灵活调节刚度和能量吸收。值得注意的是,在相对密度为0.04-0.12的范围内,比杨氏模量平均增加了47%,达到了Hashin-Shtrikman上限的177%,而比剪切模量提高了84.0%。定向属调谐使TPMS超材料在单轴载荷下获得近94%的蜂窝刚度。3D打印TPMS超材料的比能吸收随着属水平的增加,从1.77 J·g−1增加到6.93 J·g−1。总的来说,这项工作建立了属作为机械性能的基本拓扑描述符,并为开发轻量级,高度可定制的超材料提供了强大的设计范例。

Improving the fracture toughness of concrete is key to improving the resilience and longevity of structures throughout our built environment. Microstructural heterogeneity and resulting crack propagation and arrest mechanisms are central to concrete’s fracture toughness. While nanoindentation has shed light on the heterogeneity of moduli and hardness in concrete, more research is needed to understand how individual microstructural phases contribute independently and collectively to macroscopic fracture properties. Here, we combine three-point bend experiments on microbeams of concrete with pre- and post-test X-ray imaging and finite element modeling to investigate the influence of individual phases of concrete on crack propagation mechanisms. We pay careful attention to incorporating realistic fracture properties of the individual phases in modeling based on recent experiments using nanoindentation, microscratch testing, and acoustic emission. Our combined experimental and modeling study reveals that the contrast in the elastic and fracture properties of phases, and microstructural features such as the size and shape of inclusion phases, largely influence the crack propagation mechanisms and effective toughness of the concrete composite. The results provide useful insights into engineering the next generation of tough cementitious materials.
提高混凝土的断裂韧性是提高整个建筑环境中结构的弹性和寿命的关键。微观结构的非均质性和由此产生的裂纹扩展和止裂机制是混凝土断裂韧性的核心。虽然纳米压痕已经揭示了混凝土中模量和硬度的异质性,但需要更多的研究来了解单个微观结构相如何独立和共同地影响宏观断裂特性。在这里,我们将混凝土微梁的三点弯曲实验与测试前后的x射线成像和有限元建模相结合,研究混凝土各个阶段对裂缝扩展机制的影响。基于最近使用纳米压痕、微划痕测试和声发射进行的实验,我们非常注意将各个相的真实断裂特性纳入建模中。实验与模型相结合的研究表明,相的弹性和断裂性能的差异以及夹杂相的尺寸和形状等微观组织特征在很大程度上影响了混凝土复合材料的裂纹扩展机制和有效韧性。该结果为工程下一代坚韧胶凝材料提供了有用的见解。

Soft robots generally require compliant structures that support efficient actuation and reliable self-sensing. However, integrating these two functions within a single material system remains challenging. In this work, a compact magnetoelastic composite (MEC)-polyvinylidene fluoride (PVDF)-MEC sandwich structure is developed to realize intrinsic magneto-mechano-electric (MME) coupling, thereby enabling magnetic actuation together with deformation-induced electrical sensing in one integrated system. Systematic optimization of Neodymium-Iron-Born (NdFeB) filler content, MEC layer configuration, and PVDF thickness reveals a balanced magnetic torque-compliance condition, with the 50% filler, double-layer MEC, and 28 μm PVDF combination providing the highest coupling efficiency. Furthermore, the analytical model based on first-order Euler–Bernoulli beam theory and piezoelectric constitutive equation establishes a quantitative relationship between magnetic torque, structural compliance, and piezoelectric output. This theoretical framework elucidates the underlying mechanisms driving the optimization of material-structure parameters. Based on the optimized parameters, the mold-assisted magnetization-programmed MEC–PVDF–MEC sandwich structure was fabricated into butterfly-inspired, cross-shaped, and scorpion-inspired soft robots. These prototypes demonstrate capabilities in magnetic-field sensing, multimodal locomotion, and object manipulation. These results establish an integrated material–structure strategy for soft robots that enables remote actuation and self-sensing while maintaining adaptability in complex environments.
软机器人通常需要柔性结构,以支持高效的驱动和可靠的自传感。然而,将这两种功能集成到单一材料系统中仍然具有挑战性。在这项工作中,开发了一种紧凑的磁弹性复合材料(MEC)-聚偏氟乙烯(PVDF)-MEC夹层结构,以实现本构磁-机电(MME)耦合,从而在一个集成系统中实现磁驱动和变形感应电传感。通过对钕铁硼(NdFeB)填料含量、MEC层构型和PVDF厚度的系统优化,发现50%填料、双层MEC和28 μm PVDF组合具有最高的耦合效率。基于一阶欧拉-伯努利梁理论和压电本构方程的解析模型建立了磁转矩、结构柔度和压电输出之间的定量关系。这一理论框架阐明了驱动材料结构参数优化的潜在机制。基于优化后的参数,将模具辅助磁化编程的MEC-PVDF-MEC夹层结构制作成蝴蝶形、十字形和蝎子形三种形状的软体机器人。这些原型展示了磁场传感、多模式运动和物体操纵的能力。这些结果为软机器人建立了一种集成的材料-结构策略,使其能够远程驱动和自我感知,同时保持在复杂环境中的适应性。
