A general solution on stress singularities in the junction of two anisotropic materials

The general solution on stress singularities of a junction composed of two dissimilar anisotropic materials is presented in this paper. Based on the Lekhnitskiiʹs approach, the characteristic equation of the generalized plane deformation problem is developed. The influencing parameters on the stress singularity are material constants, fiber orientations and the bonding wedge angle. The results of the stress singularity order are contour plotted in a circular region. With these figures, the conditions for a minimum, or even vanishing, singularity order can be determined. The accuracy of this approach is guaranteed as the results are compared with several degenerated cases.
