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.
