review text: Functionally gradient materials (FGMs) were first introduced in Japan and attracted much attention as advanced structural materials due to their heat-resistance properties. The FGMs materials are made by combining different materials using powder metallurgy methods. They exhibit variations in constituent volume factors which leads to continuous change in composition, microstructure and porosity, and this results in changes in mechanical and temperature-dependent properties. Here the authors present an investigation of vibrations of functionally graded cylindrical shells composed of stainless steel and nickel. The study is carried out for two types of functionally graded cylindrical shells: the former has properties that vary continuously from nickel on its inner surfaces to stainless steel on its outer surfaces, and the latter vice versa. The analysis employs Love shell theory and Ritz method. The main goal is to determine how the constituent volume factors and the configuration of the constituent materials influence the natural frequencies.
