Elastic analysis of functionally graded pressure vessels rotating with a constant angular velocity using the power series method

In this study, stresses in isotropic rotating thick walled pressure vessels made of functionally graded material are investigated using elasticity theory. It is assumed that the material properties except Poisson's ratio vary in the radial direction with the Voigt model. Under these conditions, the analytical solution of the Navier equation is obtained by the power series solution method. The solutions available in the literature are used to verify the results obtained in this study. It is investigated how radial displacement, radial stress and circumferential stress are affected at different volume fraction indices for a randomly selected material pair consisting of metal and light metal.
