The full proceedings also include volumes on Structural Dynamics and Renewable Energy, Dynamics of Bridges, Dynamics of Civil Structures and, Structural Dynamics. Each collection presents early findings from experimental and computational investigations on an important area within Structural Dynamics. The current volume on Nonlinear Modeling and Applications includes studies on Nonlinear Modeling, Nonlinear System Identification, and Nonlinear Experimentation Nonlinearities in structural dynamic systems are increasingly important in advanced applications involving biological systems, advanced aircraft, complex ground vehicles, micro/nano-systems, and other structures. Nonlinear Modeling and Applications addresses a range of topics in nonlinear structural dynamics including analytical modeling and simulation, experimentation and system identification, and design, health monitoring, and control. The organizers would like to thank the authors, presenters, session organizers and session chairs for their participation in this track. The Society would like to thank the organizers of this Focus Topic, D.E. Adams, Purdue University; G. Kerschen, University of Liege for their efforts.
