numerical and analytical investigation of a cylinder made of functional graded materials under thermo-mechanical fields

this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can be developed. material properties such as modulus of elasticity are graded along the radial direction. for validation of the obtained results; a complete numerical analysis using finite element approach is presented.
