The stress field near the apex of two-phase materials formed from two isotropic homogeneous wedges with arbitrary angles under surface traction has been obtained by Bogy. The singularity in the stress field is investigated using Dundurs' composite parameters α and β. The stress singularity depends on the values of α and β, and is represented by the order O(r^<-s-2>) for α(α-2β)>0, O(log r) for α(α-2β)=0, and O(1) for α(α-2β)<0. However, the order in the displacement field has not yet been clarified. In this paper, equations of the stress field and displacement field near the apex in bonded quarter-planes of dissimilar materials under surface traction are derived for α(α-2β)<0, α(α-2β)=0 and α(α-2β)>0. It is shown that the limiting behavior r→0 for the r-direction and θ-direction displacement differs from each other.
