Dynamic Behavior of Fiber and Particle Reinforced Composites

Abstract

Develop models for wave propagation in a particle or fiber reinforced composite material in order to describe its dynamic anisotropic and dispersive properties. Compare model predictions with experimental results for inversion of anisotropic properties of the constituents. Also relate measured properties with the microstructure. Study by the modelling technique the effects of interface/ interphase on the effective properties in order to characterize interface/ interphase. Analyze the characteristics of guided waves in fiber reinforced laminated plates and shells for the characterization of anisotropic properties of a lamina. Also investigate the effect of the properties of the interface material layers (bond layers) between the laminae on the dispersion and dynamic response of guided waves. In addition, for thick laminated composites it is of interest to investigate the dispersion of guided waves in order to model them as homogeneous anisotropic media. Study the transient response of laminated composite plates due to impact. Of particular interest is the dependence of the response on the duration of impact. Analyze the maximum inter-laminar stresses for damage development
