TRANSIENT THERMOELASTIC PROBLEM OF A FUNCTIONALLY GRADED CYLINDRICAL PANEL DUE TO NONUNIFORM HEAT SUPPLY

摘要

This article is concerned with the theoretical treatment of transient thermoelastic problem involving a functionally graded cylindrical panel due to nonuniform heat supply in the circumferential direction. The thermal and thermoelastic constants of the cylindrical panel are expressed as power functions of the radial coordinate variable. The exact solution for the two-dimensional temperature change in a transient state, and thermal stresses of a simple supported cylindrical panel under the state of plane strain is obtained herein. Some numerical results are shown in figures. Furthermore, the influence of the nonhomogeneity of the material upon the temperature change, displacements, and stresses is investigated.
