000012669 520__ $$2eng$$aIn this paper, an enhanced exponential collocation method for the stability assessment of inhomogeneous Timoshenko beams subjected to a concentrated load is presented. The exponential basis functions usually adopted in the literature have been enriched with trigonometric functions that make the eigenvalue analysis well-posed without reducing the original simplicity of the method. Several examples aimed at estimating the buckling loads under typical end supports are presented and discussed. A comparison with exact and with other numerical results that are available in the literature has been carried out. Such a comparison shows the high accuracy and the fast convergence of the proposed approach.
