Analysis on Centrifugal Load Effect in FG Hollow Sphere Subjected to Magnetic Field

This paper presents the effect of centrifugal load in functionally graded (fg) hollow spheresubjected to uniform magnetic field. analytical solution for stresses and perturbation of themagnetic field vector are determined using the direct method and the power series method. thematerial stiffness, the magnetic permeability and the density vary continuously across thethickness direction according to the power law functions of radial directions. magnetic fieldresults in decreasing the radial displacement, the radial and shear stresses due to centrifugal loadand has a negligible effect on circumferential displacement and also small effect compared withthe other quantities on the circumferential stress due to centrifugal load. increasing the angularvelocity results in increasing the all above quantities due to magnetic field. with increasing thepower law indices the radial displacement, the shear and circumferential stresses due to centrifugalload and magnetic field all are decreased and the radial stress due to centrifugal load and magneticfield increased.
