Preface
Topics in Modal Analysis I represents one of six volumes of technical papers presented at the 30th IMAC, A Conference and Exposition on Structural Dynamics, 2012 organized by the Society for Experimental Mechanics, and held in Jacksonville, Florida, January 30–February 2, 2012. The full proceedings also include volumes on Dynamics of Civil Structures; Substructuring and Wind Turbine Dynamics; Nonlinear Dynamics; Model Validation and Uncertainty Quantification; and Modal Analysis II. Each collection presents early findings from experimental and computational investigations on an important area within Structural Dynamics. Modal Analysis is one of the subjects related to the broad field of Structural Dynamics that IMAC seeks to cover. The significance of Modal Analysis cannot be underestimated as is evidenced by the two volumes in this year’s proceedings dealing with this subject. The organizers would like to thank the authors, presenters, session organizers, and session chairs for their participation in this track.
