Vibrations of a Rotating Functionally Graded Cylindrical Shell under Pressure with Ring and Stringer Stiffened

In the investigation, the vibrations of a rotating functionally graded cylindrical shell under axial and internal pressure with ring and stringer stiffened and simply supported boundary condition based on Love’s shell theory is studied. The material properties of the rotating functionally graded (FG) cylindrical shell vary continuously across the thickness according to the power law distribution. In this study considers functionally graded material composed of Nickel and stainless steel, in which FG cylindrical shell has Nickel on its inner surface and stainless steel on its outer surface. The governing equations of cylindrical shell are derived using Hamilton’s principle and energy method and the effect of various parameters such as angular speed, ring and stringer stiffened, axial load, internal pressure and functionally graded material is investigated. The validity of the results by comparing them with the results in previous research is investigated, in which there is very good agreement between the results of the present work and previous studies.
