标题： Analytical modeling of laminated composite rings on nonreciprocal elastic foundations under non-axisymmetric loading

摘要： 一种层合复合环在非互易弹性基础上的机械模型是在各种应用的早期设计阶段有价值的工程工具，例如非充气轮子、柔性轴承、油井中的可扩展管状物以及与血管内膜相互作用的血管支架，尤其是在非轴对称载荷下。 尽管其重要性，但有限的研究集中在层合复合环与非互易弹性基础之间的相互作用上。 此外，尚未有定量研究探讨基础刚度对环变形的影响。 本工作旨在开发一个分析框架，用于分析在非轴对称载荷条件下由非互易弹性基础支撑的层合复合环。 该模型生成一个设计图，将基础刚度与环变形相关联，考虑环的尺寸、层压结构和单层各向异性。 闭式解提供了一个高效的分析工具，以较低的计算成本分析非轴对称和非均匀载荷。 生成的设计图为探索非互易基础与层合环之间的相互作用提供了宝贵的资源。 所提出的分析框架和设计图在汽车、机械、土木和生物医学工程领域具有广泛的应用潜力。 显示英文摘要

摘要： A mechanical model of a laminated composite ring on a nonreciprocal elastic foundation is a valuable engineering tool during the early design stages of various applications, such as non-pneumatic wheels, flexible bearings, expandable tubulars in oil wells, and vascular stents interacting with blood vessel linings, especially under non-axisymmetric loadings. Despite its importance, limited research has focused on the interaction between laminated composite rings and nonreciprocal elastic foundations. Moreover, no quantitative studies have yet explored the influence of foundation stiffness on the ring deformation. This work aims to develop an analytical framework for a laminated composite ring supported by a nonreciprocal elastic foundation under non-axisymmetric loading conditions. The model generates a design map that correlates the foundation stiffness with the ring deformation, accounting for ring dimensions, laminate layup architecture, and lamina anisotropy. The closed-form solution provides an efficient design tool for analyzing non-axisymmetric and nonuniform loadings at a low computational cost. The resulting design map provides a valuable resource for exploring the interaction between the nonreciprocal foundation and the laminated ring. The proposed analytical framework and design map hold broad potential applications in automotive, mechanical, civil, and biomedical engineering fields.
