This paper presents the derivation of nondimensional buckling equations of sandwich cylindrical shells made of composite facesheets with a shear deformable core. The procedure yields an analytical solution in terms of a series of nondimensional parameters for the axial buckling load investigating the influence of the core transverse shear. The developed equations and the nondimensional parameters are used to study the buckling response of different shells, and the calculated buckling loads are compared to the buckling values obtained by neglecting the transverse shear. Graphs and tables are presented to show the effects of the nondimensional parameters on the nondimensional buckling load. The results are verified by finite element analyses using the commercial code Abaqus.

本文提出了具有剪切可变形芯的复合面板制成的夹心圆柱壳的无量纲屈曲方程的推导。该程序针对轴向屈曲载荷的一系列无量纲参数，提供了一种分析解决方案，用于研究岩心横向剪切的影响。利用已开发的方程和无量纲参数研究了不同壳体的屈曲响应，并将计算的屈曲载荷与忽略横向剪力获得的屈曲值进行了比较。呈现图形和表格以显示无量纲参数对无量纲屈曲载荷的影响。使用商业代码Abaqus通过有限元分析验证了结果。
