Woodhead Publishing Damping in Fiber Reinforced Composite Materials (Woodhead Publishing Series in Composites Science and Engineering)

Damping in Fiber Reinforced Composite Materials starts with an introduction to the basic concepts of damping in composite materials. Methods of modeling damping are then covered, along with recent developments in measuring techniques, both local, like polar scanning and global techniques like the Resonalyser method (based on measuring modal damping ratios of composite material plates). The effect of other factors, such as stress, strain-level, stiffness and frequency that need to be considered when determining damping behavior in composite materials are also discussed in detail. Other chapters present a parametric study of a two-phase composite material using different micromechanical models such as Unified micromechanics, and Hashin and Eshelby’s to predict elastic moduli and loss factors. A bridging model that incorporates the effect of fiber packaging factors is then compared to FEM results. Final sections cover the effect of the interphase on the mechanical properties of the composite, present a nonlinear model for the prediction of damping in viscoelastic materials, and provide practical examples of damping and principles of vibration control. Review This book provides readers with an in-depth view of damping behavior in fiber reinforced composite materials From the Back Cover <p>Damping is an important parameter that is used for measuring and predicting the dynamic performance of composite materials. In this exemplary new book, the authors discuss damping behaviour in glass fiber-reinforced composite materials.</p> <p><i>Damping in Fiber Reinforced Composite Materials </i>starts with an introduction to the basic concepts of damping in composite materials. Methods of modelling damping are then discussed in chapter two. These include both macro and micro-mechanical approaches. Chapter three then goes on to discuss recent developments in measuring techniques, both local like polar scanning and global techniques like the Resonalyser method (based on measuring modal damping ratios of composite material plates). The effect of other factors such as stress, strain-level, stiffness and frequency that need to be considered when determining damping behaviour in composite materials are also discussed in detail. In chapter four a parametric study of a two-phase composite material is presented using different micromechanical models such as Unified micromechanics, and Hashin, and Eshelby’s to predict elastic moduli and loss factors. A bridging model that incorporates the effect of fiber packaging factors is then compared to FEM results. Chapter five investigates the effect of the interphase on the mechanical properties of the composite. A mathematical model is developed for prediction of elastic moduli of a three-phase fiber reinforced composite. Chapter six presents a nonlinear model for the prediction of damping in viscoelastic materials. The final chapter provides practical examples of damping and discusses principles of vibration control.</p> <p>The book will be an essential reference resource for academic and industrial researchers working in the field of composite materials, especially on the modelling and analysis of damping and dynamic behaviour.</p> About the Author Dr. Pramod Kumar attained his Ph.D in Mechanical Engineering from NIT Jalandhar.
