Abstract: An arbitrarily loaded antiplane strip shear crack situated parallel to the free surface of a semi-infinite one-dimensional hexagonal quasicrystalline material is considered. By combining an extended dislocation layer technique with a method of images, closed-form readily-calculable expressions are found for the phonon and phason stress fields' components thereby created. Some representative numerical data are discussed and presented graphically for illustration.

Keywords: quasicrystalline half-space; loaded shear crack; dislocation layers.
