The study deals with finite element analysis of sandwich cylinder made up of functionally graded (FG) material in the middle layer and outer layers as composite materials. The cylinder is under the effect of mechanical and thermal loading. Young’s modulus (i.e. elasticity modulus), thermal conductivity and coefficient of thermal expansion are varied in nonlinear form in functionally graded domain of the cylinder. The effect of thermo-mechanical loading, different material composition, and varying material properties on the behaviour of radial displacement, radial and tangential stresses is analysed. Performance of functionally graded cylinder with inner and outer composite layers is discussed with the help of graphical representation of stresses and displacement.

Keywords: functionally graded materials (FGM), Young’s modulus, thermal expansion, coefficient of thermal expansion, internal pressure, stress, displacement
