Abstract
We analize the steady propagation of a straight interfacial crack between two dissimilar quasicrystals in the infinitesimal deformation regime. A closed form solution to the balance equations is furnished. Inertia is attributed only to the macroscopic motion.The two-dimensional setting selected here allows the use of Stroh formalism, thus generalizing the method used to describe the propagation of straight cracks in bodies constituted by a single type of quasicrystals. Boundary conditions are prescribed at infinityand along the interface, including the crack.
