The objective of this work is to investigate the wave propagation characteristics of circular cylindrical shells made of three-dimensional graphene aerogel (3D-GA). Different distributions of 3D-GA inside the shells are taken into account. The first-order shear deformation (FSD) shell theory is utilized to model the present shells. Hamilton’s principle is employed to drive the equations of motion, which governs the wave propagation behavior of 3D-GA cylindrical shells. The analytical wave dispersion relations with longitudinal and circumferential wave numbers are obtained. In addition, detailed parametric studies are conducted to emphasize the influences of the porosity distribution, the porosity coefficient, the radius-to-thickness ratio, the applied forces and the elastic foundation on wave propagation characteristics of 3D-GA cylindrical shells.

这项工作的目的是研究由三维石墨烯气凝胶（3D-GA）制成的圆柱壳的波传播特性。考虑了壳内3D-GA的不同分布。一阶剪切变形（FSD）壳理论用于对当前壳进行建模。采用汉密尔顿原理来驱动运动方程，该运动方程控制3D-GA圆柱壳的波传播行为。得到了具有纵向波和圆周波数的解析波色散关系。此外，进行了详细的参数研究，以强调孔隙率分布，孔隙率系数，半径-厚度比，作用力和弹性基础对3D-GA圆柱壳的波传播特性的影响。
