Thickness of FGM disk and the material property, namely, Young’s modulus are varying exponentially in radial direction. Poisson’s ratio is considered invariant for the material. Navier equation is used to formulate the problem in the differential equation form under plane stress condition. Displacement, stresses, and strains are obtained under the influence of material gradation and variable thickness. Three different material combinations are considered for the FGM disk. The mechanical response of disk obtained for different functionally graded material combinations are compared with the homogenous disk, and results are plotted graphically1192021119202123224426https://wseas.com/journals/mechanics/2021/a525106-1501.pdf10.37394/232011.2021.16.26https://wseas.com/journals/mechanics/2021/a525106-1501.pdf10.1007/s12206-012-0908-3Nejad, M.Z., Abedi, M., Lotfian, M.H. and Ghannad, M., An exact solution for stresses and displacements of pressurized FGM thick-walled spherical shells with exponential-varying properties, Journal of mechanical science and technology, 26(12), 2012, pp.4081-4087. 10.1177/1099636219839161Dini, A., Nematollahi, M.A. and Hosseini, M., Analytical solution for magneto-thermo-elastic responses of an annular functionally graded sandwich disk by considering internal heat generation and convective boundary condition, Journal of Sandwich Structures & Materials, 23(2), 2021, pp.542-567. 10.1155/2018/1871674Jalali, M.H. and Shahriari, B., Elastic stress analysis of rotating functionally graded annular disk of variable thickness using finite difference method, Mathematical Problems in Engineering, 2018. 10.1016/j.amc.2011.06.029Temimi, H. and Ansari, A.R., A new iterative technique for solving nonlinear second order multi-point boundary value problems, Applied Mathematics and Computation, 218(4), 2011, pp.1457-1466.
