✦ Synopsis

The order of stress singularities at the apex of a wedge where the boundaries of which are allowed to be in a mixed type and the materials of which are considered to be general anisotropic is investigated. Selecting the complex function f ðzÞ to be in the form of z dþ1 in the Stroh formalism where d ðÀ1 < Re½d < 0Þ is the magnitude of the stress singularities, combined with appropriate boundary conditions under consideration, the characteristic equations for the d are then derived from which the values of d are investigated. Numerical results for the order of singularities with the extended wedge angles equal to p=2 or p and with mixed types of boundary conditions, which are discussed in the paper, are given. Furthermore, the effect of the alignment of the principal axes of the material on the order of singularities is also investigated.
