摘　　要：本文提出一种简化的用于求解软芯复合材料夹层板的一阶zigzag理论模型,该模型能精确求解外载荷作用下软芯复合材料夹层板的静态和动态响应。软芯复合材料夹层板的上下面板采用一阶剪切变形理论,芯材运用线性函数模拟横向和面内位移。模型充分考虑芯材厚度方向的应力和应变,能很好满足横向剪切应力和位移界面边界条件。基于此模型,运用Newmark法求解控制方程分析冲击载荷作用下简支软芯复合夹层板的动态响应,将提出的一阶zigzag理论模型与公开发表的文献结果进行了准确性对比验证。在验证的基础上进行了一系列的参数研究,并详细研究了各种参数对夹层板动态响应的影响。计算结果能为船用软芯复合材料夹层板提供理论设计指导。A new simple first-order zigzag theory(FZZT)was proposed for the dynamic response anal‐ysis of composite sandwich plates with soft cores through use of first-order shear deformation theory for top and bottom skins and use of linear functions for modeling of transverse and in-plane displace‐ments of the soft core by considering transverse normal strain and stress of the core.Continuity condi‐tions for transverse shear stresses and displacements at the interfaces were satisfied.Besides,an ana‐lytical solution for dynamic response analysis of simply-supported sandwich plates under impulsive loading is presented based on Navier's method,in which the Newmark method was employed to solve governing equations.The accuracy of the present theory and solution were validated by comparing with open literatures,followed by a series of parametric studies conducted to investigate influence of the dynamic response.The reseacch results can serve as a theoretical basis for structural design and application of composite sandwich plates with soft cores.
