"Modal Testing: Theory and Practice" by D. J. Ewins is an excellent book, the first published text on modal analysis. It is based on lectures given by the author and colleagues at Imperial College and courses sponsored by the Vibration Institute. The book covers modal analysis, which is used to obtain a mathematical description of dynamic or vibration behavior of structures. It includes new information from modern data acquisition and processing systems. The book has six chapters and two appendices, covering topics such as the theoretical basis of modal analysis, mobility measurements, experimental modal analysis, mathematical model derivation, and final results from modal test data. The author explains the properties of modal circles, curve-fitting methods, and the importance of residual terms. The book also discusses component mode methods, structural modification, and response prediction. The reviewer suggests that the author could have extended the section on component mode methods and provided more details on multipoint methods and experimental modal analysis. The book is recommended for engineers and analysts interested in theoretical and experimental modal analysis. "Proceedings of Third International Modal Analysis Conference" contains 190 papers from 45 sessions, covering topics such as analytical methods, experimental case histories, processing modal data, and modal test methods. The book includes extensive bibliographies and discusses various aspects of modal analysis, including the use of frequency response functions, modal confidence factors, and the application of maximum entropy response functions. The experimental case histories section includes papers on modal testing, vibration testing, and the response of steam turbine blades. The book is a valuable resource for researchers and practitioners in the field of modal analysis."Modal Testing: Theory and Practice" by D. J.
