ABSTRACT
This paper deals with the determination of thermal stresses distribution and deformations in radially graded circular arches. The study focuses on the analysis of curved beams made of functionally graded materials, where the material composition varying in the radial direction according to an arbitrary function. The arch is assumed to be under generalized plane stress state and subjected to combined thermal and mechanical loads. An arbitrary radial temperature field is prescribed, while we investigate the application possibilities of special radial surface forces applied to the upper and lower curved boundary surfaces and moments at the end cross section of the beam. The solution is derived by generalizing the semi-analytical solutions of multilayered components.
