Numerical and analytical investigation of a cylinder made of functionally graded materials under thermo-mechanical fields

Abstract

This research develops thermo-elastic analysis of a functionally graded cylinder under thermomechanical 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.
