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 a stress singularity of 1/γ^<1-λ_1> and a skew-symmetric type with a stress singularity of 1/γ^<1-λ_2>. If G_2<G_1, there exists only the singularity of skew-symmetric type, and if G_2>G_1, there exists only the singularity of symmetric type. An expression of stress fields at the close vicinity of the corner is presented. Based on the expression the singular stress fields are defined in terms of two constants K_<III,λ_1> and K_<III,λ_2> for the symmetric type and the skew-symmetric type, respectively.
