In the present paper, the plane problem for three-phase materials formed from three isotropic homogeneous wedges with arbitrary angles is analyzed. In particular, the eigenequation for the three-phase bonded structure analytically derived in the previous paper is used for investigating the effect of the elastic property for intermediate material on the order of singularity in the stress field near the apex. For the several cases in which wedge angles ψ_1, ψ_2, ψ_3 are equal and those in which ψ_1+ψ_3 and ψ_2 are constant, the order of singularity in the stress field for different material combinations and that for different wedge angles of regions 1 and 3 are studied in detail.
