In this paper investigates bending behavior of P-FGM beam resting on the elastic foundation including Winkler springs. Exact solutions obtained from closed-form formulation based on generalized shear deformation beam theory which can be adapted to various beams theories for bending analysis of such beam are presented. An accuracy of the present solutions is validated numerically by comparisons with some available results in the literature. Various significant parameters P-FGM volume fraction, spring constant factors, beam thickness, etc. are taken into investigation. According to the numerical results, it is revealed that the deflection of the beams is found to decrease as the increase of spring constant factors.
