Abstract :
A first-ever experimental validation of the electromechanical buckling response is presented. Electromechanical buckling is the coupling of two bifurcation responses: mechanical buckling and electromechanical bifurcation. In this paper, electromechanical buckling is demonstrated on a clamped-guided beam that is simultaneously subjected to an axial mechanical load and a symmetric, transverse, electrostatic field. Experimental measurements of the electromechanical buckling voltage are in good agreement with the theoretical prediction
