Abstract
Axially-loaded structures play an integral role in engineering design. Some of these structures exhibit nonlinear response behavior under harmonic loading. Methods aimed at eliminating these behaviors are often employed in design. The question, however, arises: are there any beneficial behaviors that are unknowingly being eliminated? If so, can the nonlinear dynamics be exploited for design benefits? Our hypothesis is that the nonlinear dynamics can be used to optimize system response characteristics. In this thesis, the dynamic behavior of straight and buckled beams under harmonic excitation is considered. Beam models with various sources of nonlinearity are presented and numerical methods are employed to simulate system responses. An optimization approach is formulated that achieves maximized, periodic, and stable responses of the beam systems. Case studies are presented that demonstrate the ability, efficiency and robustness of the optimization approach to exploit the nonlinear dynamics to achieve desired responses.
