Abstract:
A prismatic beam made of a behaviorally nonlinear material is analyzed under aharmonic load moving with a known velocity. The vibration equation of motion is derived usingHamilton principle and Euler-Lagrange Equation. The amplitude of vibration, circular frequency,bending moment, stress and deflection of the beam can be calculated by the presented solution.Considering the response of the beam, in the sense of its resonance, it is found that there is no criticalvelocity when the behavior of the beam material is assumed to be physically nonlinear.
