Abstract: Buckling analysis of isotropic beam based on Euler-Bernoulli beam theory EBT resting on elastic foundation is investigated in this paper. The isotropic beam is exposed to an axial compressive force. Using potential energy principle the governing equations are obtained. The critical buckling load was evaluated using Navier’s method. Numerical analysis show effect both spring constant with longitudinal wave number on critical buckling loads. Validation of the numerical findings of this paper indicates that comparing the results obtainable in the previous study shows excellent agreement. The numerical results show that critical buckling load increasing with increases spring constant.
