COMPUTATIONAL METHOD OF DYNAMIC MATERIAL CONSTANT OF COMPOSITE MATERIAL AND VOLUME FRACTION OF MATERIAL COMPONENT IN COMPOSITE MATERIAL, AND RECORDING MEDIUM

摘要

PPROBLEM TO BE SOLVED: To efficiently and quickly calculate the material constant of a composite material, and to efficiently and quickly calculate the volume fraction of the material in the composite material. PSOLUTION: For the composite material, a non-linear equation, having the effective material constant of a virtual composite material as an unknown, is prepared by defining the virtual composite material in which each of the material components is dispersed in a form of spherical particles in the matrix phase at a known volume fractions. Next, the effective material constant of the virtual composite material is found as the effective material constant of the composite material by solving the equation. In this case, the equation is a recursive equation which is obtained using the self-consistent method. The volume fraction of a material component in the composite material is computed using the equation. PCOPYRIGHT: (C)2010,JPO&INPIT
