In this investigation, study of the static and dynamic behaviors of functionally graded beams (FGB) is presented using ahyperbolic shear deformation theory (HySDT). The simply supported FG-beam is resting on the elastic foundation (Winkler-Pasternak types). The properties of the FG-beam vary according to exponential (E-FGB) and power-law (P-FGB) distributions. Thegoverning equations are determined via Hamilton’s principle and solved by using Navier’s method. To show the accuracy of thismodel (HySDT), the current results are compared with those available in the literature. Also, various numerical results are discussedto show the influence of the variation of the volume fraction of the materials, the power index, the slenderness ratio and the effect ofWinkler spring constant on the fundamental frequency, center deflection, normal and shear stress of FG-beam.
