Popis: To analyse the plasticity of quasicrystals a numerical simulation method has been developed by which shear stress is applied to a two-dimensional atomic configuration of Lennard-Jones particles. The method is based on a microconvergence relaxation procedure. We present results of simulations on a simple binary tiling which is obtained by decoration of the Tubingen triangle tiling. Slip through dislocations is observed. In contrast with periodic crystals the motion of dislocations through a quasicrystal does not leave the configuration undisturbed but creates a wall of phasons.
