An Overview of Buckling and Imperfection of Cone-Cylinder Transition under Various Loading Condition

Abstract The current paper presents a brief survey of literature relevant to buckling of cone-cylinder intersection under different loads such as (i) internal pressure, (ii) external pressure, and (iii) axial compression. The paper explores the up-to-date knowledge on the buckling of cone-cylinder intersection and highlights the areas of gap in knowledge. This is aimed at contributing to better understanding of the relevant issues such as the influence of different types of imperfections in updating the current design guideline that is found to be vital in industrial practice. The review is thematically divided into: (i) the methods adopted in the past work (i.e., how the data were obtained, type of material used, type of design with/without reinforcement), (ii) the highlight and importance of past findings, (iii) the sensitivity to imperfection and its design implications and (iv) the current design recommendation and guidelines. Finally, the current paper provides a brief state-of-the-art and presents an update of related works for the future establishment of shells design guidelines.

摘要 本论文针对锥-柱连接节点（cone-cylinder intersection）在不同载荷作用下的屈曲问题开展简要文献综述，涉及的载荷类型包括：(i)内压、(ii)外压、(iii)轴向压缩。本文梳理了当前关于该类节点屈曲的前沿研究进展，并指明了现有研究的知识空白领域。本综述旨在助力学界更深入理解相关问题——例如在更新当前工业实践中至关重要的设计准则时，各类初始缺陷所产生的影响——以期为相关研究提供支撑。本次综述按主题划分为四个部分：(i) 既往研究采用的方法（即数据获取方式、所用材料类型、带/不带加强结构的设计类型）；(ii) 既往研究成果的核心发现与研究价值；(iii) 初始缺陷敏感性及其设计层面的影响；(iv) 当前的设计建议与准则。最后，本文简要梳理了当前的研究前沿现状，并更新了相关研究成果，以期为未来壳体结构设计准则的建立提供参考。
