  I am trying to analyze the frequency response of the cantilever beam. The vector force is applied at the free end and voltage to the MFC at the same time. The purpose of the research is to determine how MFC affects the modes of the composite beam with increasing voltage. According to the literature, the modes applied should be decreases as the MFC voltage increase because force to beam in opposite direction. when I APPLY VOLTAGE TO MFC patch the amplitude of modes (1st and 2nd) start to decrees but after certain limit of voltage it start to increase instead decreasing. Please guide me on this matter.
