| Investigating the stability of cylindrical shells made of composite materials is a valuable subject in mechanical engineering due to their plethora of usages across various industries. In the present investigation, the stability behavior of graphene platelets (GPLs) enhanced nanocomposite shells is methodically examined. The calculation of the composite material's properties is conducted by utilizing the modified rule of mixtures approach. Additionally, a first-order shear deformation theory is employed in conjunction with the principle of virtual work to establish the essential differential equations for the analysis. The solution to these equations is achieved by applying Galarkin’s method, which is renowned for its accuracy and efficiency in resolving both static and dynamic problems. Verification of the formulated model is done by comparing the results with existing literature. Novel findings are presented showing the variation in buckling behavior of GPL-reinforced nanocomposite shells for assorted circumferential wave numbers. Moreover, the study delves into the impact of variations in GPLs' weight fraction, length and radius to thickness ratios, and the presence of an elastic medium on the critical buckling loads of these advanced composite shell structures. | ||
