Abstract
This dissertation contributes to the field of hysteretic system analysis by utilizing the VRM+D, a differential formulation introduced by Vaiana and Rosati, to examine the dynamic responses of mechanical systems exhibiting complex hysteretic behaviors. Through the integration of the VRM+D with the Poincaré map-based continuation method, the research systematically analyzes steady-state dynamics, stability, and bifurcation phenomena in systems characterized by complex hysteretic loop shapes. The study enhances the understanding of how loop asymmetry and complexity influence the frequency response and dynamic stability of hysteretic systems. The practical significance of the research is demonstrated through its application to advanced domains, such as mechanical metamaterials and rocking systems, where hysteresis is intentionally leveraged for vibration control and energy dissipation. Furthermore, the development of a comprehensive analytical framework for Multi-Degree-of-Freedom systems extends the scope of hysteresis modeling, offering a versatile toolset for addressing complex engineering challenges.
