Description
Summary:This paper deals with the determination of displacements and thermal stresses in radially non-homogeneous curved beams which have uniform curvature. The source of the thermal loading is a prescribed steady-state temperature field which depends on the radial coordinate. The developed analytical solution is based on the Euler-Bernoulli beam theory, furthermore the field equations of linear thermoelasticity are used to get the thermal displacements and the stress field. The material properties of the considered curved beam are arbitrary smooth functions of the radial coordinate. Examples of functionally graded materials with exponential and power law based material distributions illustrate the applications of the developed analytical method. The results are compared to results coming from finite element simulations.
