Abstract
En 中文
A quasi-3D higher-order shear deformation theory (QHSDT) with five unknowns is here employed to analyze the vibrational behavior of the honeycomb sandwich cylindrical shells reinforced with graphene nanoplatelets /polymer coatings, which consider effects of both shear and normal deformation. The equations of motion of the sandwich cylindrical shell are obtained via the Hamilton principle. Navier's technique is applied to obtain the closed-form solution for the simply-supported sandwich cylindrical shell. The accuracy and applicability of the proposed quasi-3D model are validated by comparison with existing results in the literature. Additionally, a parametric study is conducted to examine the effects of different geometrical properties of the honeycomb cells and the reinforcing GNP on the vibration response of the sandwich cylindrical shell, which is of significant interest for many modern engineering applications and their optimal design.
