Abstract

Image processing technology is utilized for numerical analysis by the homogenization method for intermetallic composites. While the asymptotic homogenization method characterizes thermo-mechanical properties of composites and localizes the deformation to the microscopic level, the digital image-based (DIB) modeling method appropriately defines a finite element (FE) model of a representative volume element (RVE), i.e., a unit cell, through the use of digitized images. The results in linear and nonlinear analyses reflect the effects of the geometric configuration of the microstructure. 1. Introduction The asymptotic homogenization method enables not only the derivation of the effective properties from the micromechanical characteristics but also the evaluation of the micromechanical b
