SELF-CONSISTENT FINITE ELEMENT METHOD FOR THE PROBLEMS OF INCLUSION AND THE AVERAGE ELASTIC PROPERTIES OF COMPOSITE MATERIALS

The paper presents a self-consistent finite element method (SCFEM) dealing with inclusion problems.Based on self-consistent model, the average elastic properties of effective medium are calculated by the finite element iteration procedure.As applications of this method, the average elastic moduli for unidirectional short-fiber composites are obtained and the effect of fiber geometry on average elastic properties of composites are investigated.The numerical results agree well with those of experiments.
