In addition, a communication success probability is formulated that accounts for the communication range and vehicle density. Information is created based on variations in the minimum speed between all vehicles. Under the framework of kinetic theory for active particles, the evolution equations governing these multiple dynamics are derived to elucidate the interactions between traffic flow, information creation, and spread.

However, these structures are inevitably subjected to continuous disturbances of static-dynamic combined loads during service life. This research explores the mechanical responses and reinforcement mechanisms of anchored cemented gangue backfill materials (CGBM) under static-dynamic combined loads. The fractal grading theory was introduced to control particle size distribution of aggregates, and the anchored cemented gangue backfill samples (CGBS) were casted by cementitious materials and waste gangue. Then, the static-dynamic combined loading tests regarding various pre-static loads (<em>P</em><sub>s</sub>), dynamic load amplitudes (<em>P</em><sub>d</sub>) and pre-tightening forces (<em>P</em><sub>t</sub>) were conducted. The results reveal that the mechanical properties, bolt axial force evolution, AE responses and failure modes of anchored CGBS exhibit marked differences. The peak stress of anchored CGBS decreases progressively with increasing <em>P</em><sub>s</sub> and <em>P</em><sub>d</sub>, while it initially increases and then decreases with increasing <em>P</em><sub>t</sub>. During dynamic loading, the irreversible strain exhibits an “accelerate-constant” increasing pattern, with corresponding hysteresis curves transitioning from “sparse-dense” characteristics. During dynamic loading, the expansion deformation induced by loading decreases, while the recoverable expansion deformation during unloading increases, resulting in a gradual decay of the upper and lower limit stresses of the bolt axial force. Stress concentration near the bolt hole region alters the stress transfer path, promoting the formation of shear failure surfaces. As the degradation effects of dynamic loading intensify, the ultimate failure mode transitions from inclined shear failure to conjugate shear failure penetrating the bolt hole. The findings offer a scientific foundation for coal gangue recycling and theoretical guidance for enhancing anchoring parameters and evaluating long-term stability of support structures along gob-side entry.</div></div>","PeriodicalId":50303,"journal":{"name":"International Journal of Non-Linear Mechanics","volume":"175 ","pages":"Article 105093"},"PeriodicalIF":2.8,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698094","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}

The classical LuGre friction model considers only the speed factor and, thus, cannot fully describe the friction characteristics of a complex SCS lifting servo system. To address this limitation, this paper proposes an improved LuGre friction model that considers the effects of weight variations and rotation of an SCS ingot. In addition, a parameter identification method is developed to estimate the friction model’s parameters. To overcome the problems in traditional optimization algorithms of easy falling into a local optimum and a slow convergence speed in multi-dimensional parameter space, this study divides the parameter identification into two stages: static and dynamic stages. Particularly, in the dynamic stage, an improved particle swarm optimization algorithm, which adopts a chaotic mapping and inertia weight nonlinear change strategy, is employed to improve the precision and convergence rate of the optimization process. The results of the experiments on an SCS lifting servo system demonstrate the high efficiency of the proposed method.</div></div>","PeriodicalId":50303,"journal":{"name":"International Journal of Non-Linear Mechanics","volume":"175 ","pages":"Article 105081"},"PeriodicalIF":2.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681455","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}

The modified solution differs from its classical counterpart mainly in that it additionally captures the directional change of the liquid pressure when the liquid-solid interface is deformed with the far-field loading. In this case, the modified solution offers a possibility of characterizing, to some extent, the geometrically nonlinear behavior of a soft elastic solid filled with liquid inclusions under relatively large external loadings. Numerical examples are presented to demonstrate the essential improvements brought by the modified solution as opposed to the classical solution in predicting the local stress field and the overall effective moduli of the homogenized liquid-solid composite materials. Since the overall framework of the modified solution is still confined to linear elasticity, however, it inevitably has some limitations in applications: it works well only for a weakly nonlinear soft matrix under moderate far-field tensile strain (for example, up to around 14 %), although it fails basically for a soft matrix under compression loadings.</div></div>","PeriodicalId":50303,"journal":{"name":"International Journal of Non-Linear Mechanics","volume":"174 ","pages":"Article 105094"},"PeriodicalIF":2.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684757","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, constructing non-intrusive reduced-order models from high-fidelity finite element models still requires considerable computational time. This paper proposes a fully parallel process to accelerate the construction of geometrically nonlinear reduced-order models. In this approach, the structure is divided into multiple partitions, each assigned to a separate processor. The reduction basis for each partition ensures displacement consistency at partition interfaces without requiring additional modal coordinates at these interfaces. The parallel process operates without inter-processor communication, making it robust and straightforward to implement.
