The plane problem for a three-phase bonded structure formed from three isotropic homogeneous rectangular wedges is analyzed using the theory of elasticity. The stress field near the apex is represented by the type Kr^<P-1>, where p depends on three shear modulus and on three Poisson's ratios, and K indicates the intensity of the singular stress field. Emphasis is placed on investigating a singular stress field at the vicinity of the intersection of the interfaces in the three-phase bonded structure and a free surface subjected to normal loading. Numerical results of K for different combinations of materials are indicated for the case where wedge angles ψ_1, ψ_2, ψ_3 are ψ_1 =ψ _2= ψ_3 =π/2. The stress behavior in the three-phase materials for the limit of r→0 is studied in detail on the basis of the numerical results.
