2010 | 477 Pages | ISBN: 1848211937 | PDF | 14 MB
Over the last 50 years, the methods of investigating dynamic properties have resulted in significant advances. This book explores dynamic testing, the methods used, and the experiments performed, placing a particular emphasis on the context of bounded medium elastodynamics. Dynamic tests have proven to be as efficient as static tests and are often easier to use at lower frequency. The discussion is divided into four parts. Part A focuses on the complements of continuum mechanics. Part B concerns the various types of rod vibrations: extensional, bending, and torsional. Part C is devoted to mechanical and electronic instrumentation, and guidelines for which experimental set-up should be used are given. Part D concentrates on experiments and experimental interpretations of elastic or viscolelastic moduli. In addition, several chapters contain practical examples alongside theoretical discussion to facilitate the readers understanding. The results presented are the culmination of over 30 years of research by the authors and as such will be of great interest to anyone involved in this field.Content: Chapter 1 Guidelines for Choosing the Experimental Set?up (pages 1-11): Jean Tuong VinhChapter 2 Review of Industrial Analyzers for Material Characterization (pages 13-24): Jean Tuong VinhChapter 3 Mechanical Part of the Vibration Test Bench (pages 25-42): Jean Tuong VinhChapter 4 Exciters and Excitation Signals (pages 43-76): Jean Tuong VinhChapter 5 Transducers (pages 77-117): Jean Tuong Vinh and Michel NuguesChapter 6 Electronic Instrumentation, Connecting Precautions and Signal Processing (pages 119-153): Jean Tuong VinhChapter 7 The Frequency Hilbert Transform and Detection of Hidden Non?linearities in Frequency Responses (pages 155-186): Jean Tuong VinhChapter 8 Measurement of Structural Damping (pages 187-208): Jean Tuong VinhChapter 9 Torsion Test Benches: Instrumentation and Experimental Results (pages 209-253): Michel NuguesChapter 10 Bending Vibration of Rod Instrumentation and Measurements (pages 255-270): Dominique Le NizheryChapter 11 Longitudinal Vibration of Rods: Material Characterization and Experimental Dispersion Curves (pages 271-303): Yvon Chevalier and Jean Tuong VinhChapter 12 Realization of Le Rolland?Sorin's Double Pendulum and Some Experimental Results (pages 305-333): Mostefa Archi and Jean?Baptiste CasimirChapter 13 Stationary and Progressive Waves in Rings and Hollow Cylinders (pages 335-365): Yvon Chevalier and Jean Tuong VinhChapter 14 Ultrasonic Benches: Characterization of Materials by Wave Propagation Techniques (pages 367-395): Patrick GarceauChapter 15 Wave Dispersion in Rods with a Rectangular Cross?Section: Higher Order Theory and Experimentation (pages 397-452): Maurice Touratier
