Abstract

In the present paper, nonlinear radial and hoop THERMOELASTIC STRESSes analysis of a disk made of FGMs material is investigated. According to this purpose, FINITE ELEMENT METHOD is used. In the present method, second-order one-dimensional element (with three node points) is proposed. The geometrical and stress boundary conditions are defined in the state of non-existence of external pressure and then zero radial stress in the outer layer of the disk, and zero displacement in the center of the disk. Also the temperature distribution is assumed as linear. The material properties changes including TEMPERATURE-DEPENDENCY are modeled. Finally, a numerical example is proposed to show the radial displacements, radial and hoop THERMOELASTIC STRESSes versus radius of the disk for different power (N) from Power-law and different angular velocities. The results show that by increasing both two parameters, N and angular velocity of the disk, the amounts of displacement and stress are increased. At last, TEMPERATURE-DEPENDENCY and temperature-independency of material properties is investigated.
