✦ Synopsis

The reduction of the elastic parameters necessary to describe the stress field in a composite under plane deformation is discussed based on the body force method and the eigenstrain theory. When the composite body subjected to prescribed surface tractions consists of N different elastic phases and each phase. is characterized by M, (y = 0, 1, . , N -1) independent elastic constants, the stress fields generally depend on (:r:G M,) -1 parameters involving the elastic constants. If the vector sums of the tractions on holes vanish for every individual hole, however, the stress depends on the elastic constants through only (Efz,,' M,) -2 parameters formed from Zr:,' M, elastic constants.
