Abstract
Functionally graded materials (FGMs) are designed for specific purpose and applications. Functionally graded materials for bi-layered cylindrical shell was discussed for different boundary conditions. Functionally graded materials (FGMs) are that kind of material in which function and formation may deviate continuously. Cylindrical shells are mainly significant in various fields of science as well as advanced technology of engineering like aerospace engineering, mechanical engineering and civil engineering. Wide applications of cylindrical shell in different fields like aircraft, aerospace and pressure vessels etc. Bilayered cylindrical shells consist of two layers and in this work, one layer is of FGM material whose constituents are nickel (Ni) and zirconia (Zr) and other is of isotropic material whose constituent is stainless steel. In this work, effect of trigonometric volume fraction law on cantilever FGM bi-layered cylindrical shell with internal pressure has analyzed by using Rayleigh-Ritz technique and Love's shell theory. Present results of FGM bi-layered cylindrical shell are compared with FGM cylindrical shell. Validity of present technique has verified by way of comparisons with current conclusions and those obtained in the past studies.
