Three-Dimensional Thermo-Elastic Analysis of a Rotating Cylindrical Functionally Graded Shell Subjected to Mechanical and Thermal Loads Based on the FSDT Formulation

Resumo

This paper presents a three-dimensional thermo-elastic analysis of a rotating cylindrical functionally graded shell subjected to inner and outer pressures, surface shear stresses due to friction, an external torque, and a uniform temperature distribution. A power-law distribution is considered for thermal and mechanical properties of the material. The first-order shear deformation theory (FSDT) is employed to express the displacement field. The system of six constitutive differential equations of the problem includes the Euler equations for the energy functional. It is found that the material grading index has a significant effect on the stress and displacement fields.
