This paper presents an analysis of the stability of Timoshenko beams which uses Eringen'snonlocal elasticity theory. A numerical algorithm based on the exact solution for the freevibration of segmental Timoshenko beams was formulated. The algorithm enables one tocalculate, with any degree of accuracy, the critical load levels in the beams on the macro andnanoscale. The beams were subjected to conservative and nonconservative static loads. Thelevels of critical loads in the beams were analysed assuming a functional dependence of thenonlocal parameters on the vibrational frequency and the state of stress.
