Abstract In this paper, we have conducted finite element analysis of thick-walled sandwich cylinder with inner layer made up of functionally graded material (FGM) and outer layer as composite. The response of sandwich cylinder subjected to internal as well as external pressure and thermal loading is analysed. Material properties of FGM are tailored from inner to outer radii in an exponential form. The modulus of elasticity is decreasing from inner to outer radii in FGM, whereas thermal conductivity and coefficient of thermal expansion are increasing from inner to outer radii. Results for radial and tangential stresses as well as displacement in the sandwich cylinder with different reinforcement of SiCp in Al matrix are plotted and discussed. The effects of mechanical and thermomechanical stresses on sandwich composition of thick-walled cylinder is analysed. Keywords: functionally graded material (FGM), thick-walled cylinder, stress-strain, modulus of elasticity, thermal conductivity, thermal expansion |
