碩士 === 中華科技大學 === 飛機系統工程研究所 === 99 === Thermoelastic problems involving rotating disks have been popular in engineering applications, such as brakes, circular saws, gears, rotors etc. Theoretically, they are boundary value problems involving thermal and mechanical loadings. Therefore, the present thesis investigates the thermoelastic problems of functionally graded variable-thickness rotating discs subject to heat source by using the finite-element computer code ABAQUS with user subroutines. In addition, the corresponding analytical solutions are derived and provided by the computing software Mathematica. Different and interesting thermoelastic behavior is revealed by various parametric studies. Finally, the present research results can be extended further to other applications, e.g. thermal/mechanical analysis, laser machining, fracture mechanics, vibrations and acoustics etc.
