ELASTIC-PLASTIC FINITE ELEMENT ANALYSIS OF HYBRID SHORT FIBER+PARTICLE REINFORCED METAL MATRIX COMPOSITES

摘要

Micromechanical modeling of heterogeneous materials, including discontinuously reinforced metal matrix composites (MMCs), continues to play a substantial role in the development of new materials systems. Numerical analysis for micromechanical modeling seems to be well suited to describe the behaviors of these composites. Above all, the use of representative volume element (RVE) or unit cell of the composite microstructure, together with finite element analysis tool is well established for the investigation of effective material properties and/or to understand micromechanics of the composite materials. RVE modeling should be typical of the whole composite microstructure and contains a sufficient number of inclusions for the apparent overall properties to be effectively independent of the boundary condition.
