Two-dimensional line defects in anisotropic elastic solids

The Stroh formalism and analytic continuation approach are used to develop a systematic study for two-dimensional line defects in anisotropic elastic solids. The line defects are classified as either belonging to the craze type or line inhomogeneity type. A crack and rigid line are considered as two special cases of these categories. The governing equations, given in terms of the Stroh matrix notation, show many complementary features between these two line defects. In addition, a discussion is given showing why the line defect field cannot in general be developed from the Eshelby inclusion solution [1], except for the special cases of a crack and rigid line inhomogeneity.
