Stability of Timoshenko beams with frequency and initial stress dependent nonlocal parameters
This paper presents an analysis of the stability of Timoshenko beams which uses Eringen’s nonlocal elasticity theory. A numerical algorithm based on the exact solution for the free vibration of segmental Timoshenko beams was formulated. The algorithm enables one to calculate, with any degree of accuracy, the critical load levels in the beams on the macro and nanoscale. The beams were subjected to conservative and nonconservative static loads. The levels of critical loads in the beams were analysed assuming a functional dependence of the nonlocal parameters on the vibrational frequency and the state of stress.
