Elastic Parameters Influencing Stress Fields in Multiphase Composite

Abstract

By using the body force method, in which stress field in a composite of multiphases is treated as if it exists in an infinite plate of homogeneous phase, the Dundurs parameters a and β are extended to multiphases. When a composite contains n-phases, the stress field induced by prescribed tractions depends only on 2( n - 1) parameters ap and βp (P=1, …, n-1), provided that the vector sums of tractions on holes are zero for every individual hole.
