In the field of stress analysis of adhesive-bonded joints, many mathematical models have been developed to analyze joints composed of a single-layered isotropic material or a homogenized layered composite material as adherends that are subjected to only one type of loading. Despite being useful in the design process, these models are unquestionably too limited for real-world applications because joints are inevitably exposed to various types of loads in changing environments. Therefore, this study aims to formulate a new unified theory of adhesive-bonded cylindrical coupler joints under a wide variety of axisymmetric loading conditions. The loading scenarios include torsion, tension, internal and external pressure, and changes in temperature and moisture. The joints can consist of isotropic, orthotropic, or laminated composite adherends bonded together by a thin adhesive layer. The governing equations of the joint are simplified to be second order ordinary differential equations, which can be analytically solved in closed forms for isotropic adherends or numerically solved for anisotropic adherends. The effects of the fiber orientation on symmetric-balanced laminated composite adherends for each load are comprehensively reported. The present models are rigorously validated through comparison with the finite element method performed in ABAQUS™. Comparable to high-fidelity finite element analysis, the present theory can accurately predict three-dimensional stress fields in tubular joints made of any practical elastic materials and geometric dimensions.

具有多种轴对称载荷的不同被粘物的胶粘管接头的统一理论

在胶粘接头应力分析领域,已经开发了许多数学模型来分析由单层各向同性材料或均质层状复合材料作为被粘物组成的接头,它们仅承受一种类型的载荷。尽管在设计过程中很有用,但这些模型对于实际应用来说无疑太有限了,因为关节在不断变化的环境中不可避免地暴露于各种类型的负载。因此,本研究旨在在各种轴对称载荷条件下制定一种新的胶粘圆柱耦合器接头的统一理论。加载场景包括扭转、张力、内部和外部压力以及温度和湿度的变化。关节可以由各向同性、正交各向异性、或层压复合被粘物通过薄粘合剂层粘合在一起。接头的控制方程简化为二阶常微分方程,对各向同性被粘物可采用封闭形式解析求解,对各向异性被粘物可数值求解。综合报道了纤维取向对每个载荷的对称平衡层压复合材料粘附体的影响。通过与 ABAQUS™ 中执行的有限元方法进行比较,对当前模型进行了严格验证。与高保真有限元分析相比,本理论可以准确预测由任何实际弹性材料和几何尺寸制成的管接头中的三维应力场。接头的控制方程简化为二阶常微分方程,对各向同性被粘物可采用封闭形式解析求解,对各向异性被粘物可数值求解。综合报道了纤维取向对每个载荷的对称平衡层压复合材料粘附体的影响。通过与 ABAQUS™ 中执行的有限元方法进行比较,对当前模型进行了严格验证。与高保真有限元分析相比,本理论可以准确预测由任何实际弹性材料和几何尺寸制成的管接头中的三维应力场。接头的控制方程简化为二阶常微分方程,对各向同性被粘物可采用封闭形式解析求解,对各向异性被粘物可数值求解。综合报道了纤维取向对每个载荷的对称平衡层压复合材料粘附体的影响。通过与 ABAQUS™ 中执行的有限元方法进行比较,对当前模型进行了严格验证。与高保真有限元分析相比,本理论可以准确预测由任何实际弹性材料和几何尺寸制成的管接头中的三维应力场。综合报道了纤维取向对每个载荷的对称平衡层压复合材料粘附体的影响。通过与 ABAQUS™ 中执行的有限元方法进行比较,对当前模型进行了严格验证。与高保真有限元分析相比,本理论可以准确预测由任何实际弹性材料和几何尺寸制成的管接头中的三维应力场。综合报道了纤维取向对每个载荷的对称平衡层压复合材料粘附体的影响。通过与 ABAQUS™ 中执行的有限元方法进行比较,对当前模型进行了严格验证。与高保真有限元分析相比,本理论可以准确预测由任何实际弹性材料和几何尺寸制成的管接头中的三维应力场。
