摘　　要：复合材料已经广泛应用于航空航天、汽车、船舶、能源等众多工程领域,成为现代轻质高性能结构设计的核心材料,但其独特的复杂性给传统分析理论带来了前所未有的挑战。为了进一步发挥复合材料结构的优势,迫切需要发展先进的力学分析方法。系统梳理复合材料层合板壳结构分析理论的研究现状,重点介绍和评述几类代表性的分析理论,包括剪切变形理论、逐层理论、扩展逐层理论、状态空间理论以及多尺度分析方法,分析其在克服复合材料结构复杂性方面的作用和局限性。同时,系统总结了加筋和夹芯复合材料结构的建模方法研究进展。在此基础上,凝练了复合材料层合板壳力学在非线性、多尺度、多物理场耦合等方面面临的关键科学问题,并对今后的重点发展方向进行了展望。研究表明,发展三维精确化逐层理论、融合数据驱动计算力学与层合理论、构建跨尺度多物理场分析方法等将是未来复合材料层合板壳力学的研究热点,多种理论方法的融合与创新将是攻克复杂问题的有效途径。The composite materials have been widely used in many engineering fields,such as aerospace,automotive,shipbuilding,and energy,becoming the core material of modern lightweight and high-performance structural design.However,their unique complexity poses unprecedented challenges to the traditional analysis theories of composite laminated shell structures.To further exploit the advantages of composite structures,there is an urgent need to develop advanced mechanical analysis methods.This paper aims to systematically review the research status of analysis theories for composite laminated shell structures,focusing on introducing and evaluating several representative analysis theories,including shear deformation theories,layerwise theories,extended layerwise theory,state space theory and multi-scale analysis methods,and analyzing their roles and limitations in overcoming the complexity of composite material structures.At the same time,this paper also systematically summarizes the research progress of modeling methods for stiffened and sandwich composite structures.On this basis,the key scientific issues faced by the mechanics of composite laminated shells in nonlinearity,multi-scale,and multi-physical field coupling are summarized,and the future key development directions are prospected.Research shows that developing three-dimensional precise layerwise theories,integrating data-driven computational mechanics with layerwise theories,and constructing multi-scale multi-physical field analysis methods will be the research hotspots of composite laminated shell mechanics in the future,and the integration and innovation of various theoretical methods will be an effective way to overcome complex problems.
