The Elastic-Plastic Micromechanical Response of the Particle Volume Fraction and the Average Size of Particles
Authors: ,
Abstract: In microstructural parameters, the particle volume fraction and the average size of particles are important factors which determine the mechanical properties of materials. While, studies of three-dimensional microstructure-property relationships are still less. In this research, for two-phase materials, we have calculated elastic-plastic micromechanical responses of the particle volume fraction and the average size of particles using a commercial software package, as a basic study of three-dimensional microstructure-property relationships, in which the 3-D FEM is used. Although the grain sizes and the grain shapes of the actual materials are non-uniform, we use a simple virtual material model with particles of uniform size and shape to investigate the influence of the average size of the particles. In order to investigate the elastic-plastic micromechanical response of the particle volume fraction, two kinds of the particle volume fraction are used. By analyzing the calculated results of Von Mises stress, the equivalent plastic strain, and the curve of average tensile stress – tensile rate, some new knowledges on three-dimensional microstructure-property relationships have obtained. The advantage of using the 3-D FEM is that it is possible to study the three-dimensional microstructure-property relationships by easily and inexpensively changing various microstructural parameters (not only the particle volume fraction and the average size of particles).
