Many times, nonlinearities are seen as a burden in the design process as they can result in unpredictable and extremely sensitive response. As such, engineers make design changes to effectively minimize or completely eliminate the nonlinear behavior. In this paper, the periodic response of a buckled beams under piezo-excitation is considered. An optimization approach, as first demonstrated in [1], is utilized that achieves maximum amplitude, periodic, and stable responses of the beam systems. Case studies are presented that demonstrate the utility of this optimization approach to exploit the nonlinear dynamics to achieve desired responses.
