11 - Developments and Modeling of Electrical Conductivity in Composites

Abstract

Electrical conductivity of materials is a critical property in electronic applications. The modeling of electrical conductivity is a cost-effective pathway for determining electrical conductivity in two- or multiconstituent materials. There are several methods for modeling of electrical conductivity in composites categorized into three major classes: simulation methods, analytical–mathematical methods, and image processing methods. In this paper, an overall overview on all these methods is presented and reviews each model, separately. Many efforts have been accounted for description of modeling methods such as micromechanics models, simulation based on Monte Carlo methods, resistor models, analytical models, mathematical models, image processing. At the end, a comprehensive evaluation upon different models with emphasis on their advantages and disadvantages is developed.
