Handbook of Experimental Structural Dynamics

This book provides comprehensive coverage of experimental methods in structural mechanics. It details practical methods and focuses on important concepts, methods, techniques in use of instrumentation without commercial bias.

The SEM Handbook of Experimental Structural Dynamics stands as a comprehensive overview and reference for its subject, applicable to workers in research, product design and manufacture, and practice. The Handbook is devoted primarily to the areas of structural mechanics served by the Society for Experimental Mechanics IMAC community, such as modal analysis, rotating machinery, structural health monitoring, shock and vibration, sensors and instrumentation, aeroelasticity, ground testing, finite element techniques, model updating, sensitivity analysis, verification and validation, experimental dynamics sub-structuring, quantification of margin and uncertainty, and testing of civil infrastructure. Chapters offer comprehensive, detailed coverage of decades of scientific and technologic advance and all demonstrate an experimental perspective. Several sections specifically discuss the various types of experimental testing and common practices utilized in the automotive, aerospace, and civil structures industries.

Contributions present important theory behind relevant experimental methods as well as application and technology. Topical authors emphasize and dissect proven methods and offer detail beyond a simple review of the literature. Additionally, chapters cover practical needs of scientists and engineers who are new to the field. In most cases, neither the pertinent theory nor, in particular, the practical issues have been presented formally in current academic textbooks. Each chapter in the Handbook represents a 'must read' for someone new to the subject or for someone returning to the field after an absence. Reference lists in each chapter consist of the seminal papers in the literature.

This Handbook stands in parallel to the SEM Handbook of Experimental Solid Mechanics, where this Handbook focuses on experimental dynamics of structures at a macro-scale often involving multiple components and materials where the SEM Handbook of Experimental Solid Mechanics focuses on experimental mechanics of materials at a nano-scale and/or micro-scale.

Dr. Allemang is a Professor Emeritus and member of the faculty of the Mechanical Engineering Program in Mechanical and Materials Engineering, University of Cincinnati, where he currently also serves as Director of the Structural Dynamics Research Laboratory (UC-SDRL). Dr. Allemang has been actively involved in the area of experimental structural dynamics and modal analysis for over forty years, pioneering the use of multiple input, multiple output estimation of frequency response functions, developing the concept of cyclic averaging, formulating the modal assurance criterion (MAC) and the enhanced frequency response function and reformulating modal parameter estimation algorithms into the unified matrix (coefficient) polynomial approach (UMPA). Dr. Allemang has served on the Advisory Board for the International Modal Analysis Conference (1981-2015, Chairman, 1986- 1995), on the Editorial Board of Sound and Vibration Magazine (1983-2017) and on the Scientific Committee of the ISMA Noise and Vibration Conference at the Katholieke University of Leuven, Belgium (1984- present). Dr. Allemang has also served on the Executive Board of the Society for Experimental Mechanics (SEM) from 1998-2006, including President for the Society during 2003-2004. Dr. Allemang is currently involved as Senior Collaborator for the AFRL Structural Sciences Center at WPAFB, working on the verification and validation (experimental quantification of margin and uncertainty) of experimental and analytical dynamic models and has been recognized by three professional societies as a Fellow (SEM, SAE and ASME). Dr. Allemang has also mentored two PhD graduates who went on to win Presidential Early Career Award for Scientists and Engineers (PECASE).
