The Conference Proceedings of the Society for Experimental Mechanics Series presents early findings and case studies from a wide range of fundamental and applied work across the broad range of fields that comprise Experimental Mechanics. Series volumes follow the principle tracks or focus topics featured in each of the Society’s two annual conferences: IMAC, A Conference and Exposition on Structural Dynamics, and the Society’s Annual Conference & Exposition and will address critical areas of interest to researchers and design engineers working in all areas of Structural Dynamics, Solid Mechanics and Materials Research
Experimental Nonlinear Dynamics, Jointed Structures: Identification, Mechanics, Dynamics, Nonlinear Damping, Nonlinear Modeling and Simulation, Nonlinear Reduced-Order Modeling, Nonlinearity and System Identification , Nonlinearities & Applications, Nonlinear Normal Modes & Interactions
