Abstract

SiC_f/Ti composite thin-walled tubes exhibit a variety of fracture modes due to their complex structures and intricate manufacturing process, limiting their application. Specifically, accurate prediction of failure behavior is crucial for improving the performance of SiC_f/Ti composite thin-walled tubes. In this study, a generic multi-scale analytical model was established to evaluate the mechanical properties and failure behavior of SiC_f/Ti composite thin-walled tubes under uniaxial compression, and damage evolution and stress distribution at two scales were analyzed. At the macroscopic level, a three-dimensional Hashin-based orthotropic damage model was implemented through a user-defined subroutine (VUMAT), including damage initiation, stiffness degradation, and constitutive relationships. At the mesoscopic level, three mesoscopic models of different fiber distributions were developed based on random sequential addition (RSA) algorithm and representative volume element (RVE), and the mechanical behavior of the fiber/matrix interface was characterized by cohesive zone model (CZM). Subsequently, the nodal displacement of the macroscopic model was imposed on the mesoscopic model as the boundary condition, forming a strong coupling relationship at different scales. Furthermore, the influence of interfacial modeling approach on the buckling behavior and mechanical properties was particularly considered, and the interactions among capsule yield strength, capsule thickness, and fiber distribution were also integrated to discuss their effects on the damage evolution and stress distribution of SiC_f/Ti composite thin-walled tubes. The results indicate that the multi-scale model can accurately capture the crack initiation, propagation and failure in SiC_f/Ti composite thin-walled tubes. Moreover, the overall strength of SiC_f/Ti composite thin-walled tubes can be significantly improved as the capsule strength increases or the outer capsule thickness increases. Notably, the stress variation along the axial direction of the composite core is similar to that of the inner capsule, while the outer capsule exhibits an opposite stress trend. The multi-scale method proposed in this work provides a fresh perspective for the design of SiC_f/Ti composites thin-walled tubes.

压缩载荷下SiCf/Ti复合材料薄壁管力学性能及破坏行为的多尺度分析

SiCf/Ti复合薄壁管结构复杂，制造工艺复杂，断裂模式多样，限制了其应用。具体来说，准确的失效行为预测对于提高SiCf/Ti复合材料薄壁管的性能至关重要。本研究建立了SiCf/Ti复合材料薄壁管单轴压缩力学性能和破坏行为的通用多尺度分析模型，分析了两个尺度下的损伤演化和应力分布。在宏观层面，通过用户自定义子程序（VUMAT）实现基于哈欣的三维正交各向异性损伤模型，包括损伤起始、刚度退化和本构关系。在细观层面，基于随机顺序加法（RSA）算法和代表性体积元（RVE）建立了不同纤维分布的3种细观模型，并利用内聚区模型（CZM）表征了纤维/基体界面的力学行为。随后，将宏观模型的节点位移作为边界条件施加到细观模型上，在不同尺度上形成强耦合关系。在此基础上，重点考虑了界面建模方法对SiCf/Ti复合材料薄壁管屈曲行为和力学性能的影响，并综合考虑了包膜屈服强度、包膜厚度和纤维分布三者之间的相互作用，讨论了它们对SiCf/Ti复合材料薄壁管损伤演化和应力分布的影响。结果表明，该多尺度模型能较准确地捕捉SiCf/Ti复合材料薄壁管裂纹的萌生、扩展和破坏过程。同时，SiCf/Ti复合薄壁管的整体强度随着胶囊强度的增加或外胶囊厚度的增加而显著提高。值得注意的是，复合岩心沿轴向的应力变化与内胶囊相似，而外胶囊的应力变化趋势相反。本文提出的多尺度方法为SiCf/Ti复合材料薄壁管的设计提供了新的思路。

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
