Abstract:
Recently, by improvement of technology using piezoelectric materials to increase load capacity, the enhancement of beam characterization has gained great attention.In this paper two piezoelectric patches have been attached to an Euler-Bernoulli beam in order to investigate the effects of the position and the length of piezoelectric actuator and also the effects of boundary conditions on natural frequency, vibration behavior and mechanical stability of the beam under axial force. The patches have been attached symmetrically to upper and lower surfaces of the beam. The derived equation of motion is solved and the vibration behavior and the effects of different parameters like axial load, applied voltage, position and length of piezoelectric patches on natural frequencies and the critical load of the beam are investigated.
