Analysis of Functionally Graded Cylinders Subjected to Internal Pressure

Abstract

In the present study, A functionally graded cylinder subjected to internal pressure has been analyzed using the finite element method based software ANSYS. The variations of properties of the functionally graded material are considered based on a power-law function. The inner and outer surfaces of the cylinder are made of alumina and C45 steel respectively. The continuous composition of the two materials has been considered in the form of varying elastic modulus and Poisson’s ratio along the radial direction as the power-law function. The result of present approach is compared with analytical result of available literature. The comparison represents good coincidence between analytical and numerical results and confirms the accuracy of solutions presented in the present approach for cylinder made up of FGM. Further the stress distribution of FGM made cylindrical shell for given pressure load conditions have analyzed. Stress distributions along the radial direction are studied. The obtained result shows that the property of FGMs has a significant influence to the deformation and stress distribution along the radial direction. Numerical results presented are useful for engineer to design a cylinder made of FGMs
