Abstract
The mechanism of plastic deformation in quasicrystals is dislocation motion , Dislocations leave in their wake a phason wall where the structure is wea kened. Cracks emit dislocations and follow the phason wall. These processes are revealed by large scale molecular dynamics simulations employing the p ackage IMD. (C) 1999 Elsevier Science B.V.
