Abstract: Static bending analysis of functionally graded materials FGM beam subjected to the distributed transverse load resting on elastic foundation is investigated based on Reddy beam theory RBT. Shear modulus and Young's modulus are changes in thickness direction of the beam. The governing equations of equilibrium of FGM beam are derived based on total potential energy theory. Through numerical analysis and using the Navier’s method, the maximum transverse deflection is found. Effects both spring and shear constants with power law grading index of FGM on deflection are discussed. Using numerical results from the literature, we found this paper's results to be in a good agreement. The maximum deflection increases with increase in the values of both spring and shear constants.
