In this paper the characteristics of the stress fields near a corner of jointed dissimilar materials under antiplane loads are studied. It is found that the singular stress fields due to the antiplane loads can be divided into two types: a symmetric type with the stress singularity of 1/r^<1-λ_1> and a skew-symmetric type with the stress singularity of 1/r^<1-λ_2>. If G_2<G_1, there exists only singularity of the skew-symmetric type, and if G_2>G_1, there exists only singularity of the symmetric type. An expression of stress field in the vicinity of the corner is presented. Based on this expression, the singular stress field is described always in terms of the constant K_<III,λ_1> for the symmetric type or the constant K_<III,λ_2> for the skew-symmetric type alone.
