AN ANALYSIS OF THE MODELING OF STRESS AND STRAIN FIELDS IN A REAL MICROSTRUC-TURE USING A HYBRID METHOD

摘要

The distribution of stress and strain fields in a micro-structural area of a" particle reinforced composite is studied by a combination of experimental and numerical method (hybrid method). With the experimental values of displacements in a micro-region as the boundary loading condition, strain and stress fields inside the micro-region are calculated by the finite element method under two different kinds of modeling, namely, as plane stress and plane strain condition. The differences between the two kinds of modeling conditions as applied to micro-structural areas are discussed.
