This cross-component 2:1 excitation mechanism, where the external load is applied to the beam but the nonlinear response emerges in the cable, has rarely been examined despite its potential to trigger large-amplitude cable vibration. To address this problem, a reduced-order cable–beam coupled model is formulated using Hamilton’s principle, retaining the essential quadratic and cubic coupling terms responsible for nonlinear energy transfer. The method of multiple scales is employed to analytically reveal the formation mechanism and amplitude–frequency characteristics of the cable’s 1/2-order subharmonic response. To suppress this nonlinear vibration, a time-delayed velocity feedback strategy is introduced into the cable equation. Furthermore, a semi-active control scheme based on a magnetorheological (MR) damper is developed, where a mapping algorithm is adopted to reproduce the desired delayed control force. Numerical simulations demonstrate that the proposed control method effectively eliminates subharmonic resonance and stabilizes the cable response. The findings provide new theoretical insight into nonlinear coupling-induced subharmonic vibration and offer practical guidance for vibration control in long-span cable-supported bridges.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"330 ","pages":"Article 113880"},"PeriodicalIF":3.8,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FEM is then used to obtain forming force–displacement curves under various process parameter conditions. By identifying the intersection between the simulated forming force curves and the theoretical limit load curve, the fracture height, representing the maximum drawing limit, is determined and validated against experimental data from literature, confirming the accuracy and effectiveness of the proposed approach. Building upon this, a comprehensive dataset of forming forces is generated using FEM under a wide range of process conditions, including variations in the coefficient of friction, die radius, punch radius and blank holder force. This dataset is used to train a GRU neural network model to enable rapid prediction of the drawing force. Finally, by combining the GRU-predicted force curves with the analytically derived load-bearing capacity, the maximum punch displacement under arbitrary process parameters was efficiently obtained. The findings indicate that the proposed approach delivers accurate predictions and exhibits robust generalization performance, while significantly reducing the computational cost associated with process parameter optimization.

As a result, these models are unable to accurately predict certain qualitative electroactive deformation behaviors, including electromechanical instability. To address this limitation, this work develops a mechanical elastic constitutive description within an EMO coupling framework by incorporating both transversely isotropic elasticity and strain stiffening. The resulting model is used to investigate homogeneous anisotropic electroactive deformations and associated instability behaviors of monodomain DNE films, and 3D finite element simulations are further performed to study inhomogeneous electroactive deformations with spatially varying director orientations.

This paper establishes a Smoothed Particle Hydrodynamics (SPH) model integrated with a physical interface interaction model to predict the adhesion strength of cold spray particles. The model simulates the formation of metal-to-metal connections between particle and substrate and utilizes the stable attractive forces generated post-bonding to enable direct numerical prediction of adhesion strength. The results indicate that adhesion strength increases nonlinearly with impact velocity, with the rate of increase gradually slowing, which is closely linked to jetting and inward curling behavior at the particle periphery. The predictions show good agreement with experimental data, validating the model’s effectiveness. Furthermore, applying this method to deposition processes under various process parameters (spray angle, particle size, and initial temperature) systematically reveals quantitative relationships between these parameters and adhesion strength, demonstrating the model’s potential for optimizing process windows and tailoring performance. Overall, this study provides a physics-based numerical tool for understanding and enhancing the bonding performance of cold spray coatings.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"330 ","pages":"Article 113875"},"PeriodicalIF":3.8,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, systematic investigations, particularly theoretical studies, remain limited. In this work, a comprehensive study is conducted on the out‑of‑plane crashworthiness of a prototypical chiral topology, namely the wavy tri‑chiral honeycomb (WTCH). The configuration of the WTCH can be interpreted as a transformation of the conventional hexagonal honeycomb (CHH), achieved by substituting its straight cell walls with curved segments. Finite element (FE) simulations are first performed to elucidate the out-of-plane crashworthiness and underlying deformation mechanism of the WTCH. Under quasi-static loading condition, three distinct collapse modes, i.e., progressive folding, concertina-like buckling, and global bending, are identified, governed by a trade-off between wave slope and cell wall slenderness ratio. The latter two modes are characterized by significantly elevated peak stresses, rendering them unfavorable for energy-absorbing applications. In contrast, under dynamic loading conditions, all WTCH configurations exhibit a progressive folding collapse mode. Based on the identified deformation mechanism, theoretical models for predicting the plateau stresses of the WTCH undergoing progressive folding collapse are developed using the Simplified Super Folding Element (SSFE) theory and validated against numerical simulations, showing strong agreement. Finally, a quantitative comparison with the CHH demonstrates that the WTCH achieves at least a 47 % improvement in specific energy absorption under identical cell size and relative density, along with consistently higher crush force efficiency. These findings provide valuable insights for the structural optimization and engineering applications of wavy chiral honeycombs in crash protection and safety contexts.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"329 ","pages":"Article 113873"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
