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

摘要

The distribution of stress and strain fields in a micro-structural area of a particle reinforcedcomposite is studied by a combination of experimental and numerical method(hybrid method).With the ex-perimental values of displacements in a micro-region as the boundary loading condition,strain and stressfields inside the micro-region are calculated by the finite element method tmder two different kinds of model-ing,namely,as plane stress and plane strain condition.The differences between the two kinds of modelingconditions as applied to micro-structural areas are discussed.
