In a large number of experiments it has been proven that plastic deformation of quasicrystals can occur by a dislocation mechanism. By the use of molecular dynamics simulations, we have investigated the application of shear stress to a three-dimensio

In a large number of experiments it has been shown that plastic deformation of quasicrystals can occur by a dislocation mechanism. By molecular dynamics simulations close to zero temperature we have investigated the application of shear stress to a t

The concept of generalized stacking faults and the associated gamma-surfaces provides a useful tool for the analysis of dislocation core structures in crystalline materials. Applied to quasicrystals, suitable Burgers vectors for a given slip plane ca

A dislocation moving through a quasicrystal is leaving in its wake a fault denoted phason wall. For a two-dimensional model quasicrystal the disregistry energy of this phason wall is studied to determine possible Burgers vectors of the quasicrystalli

Crack propagation is studied in a two dimensional decagonal model quasicrystal. The simulations reveal the dominating role of highly coordinated atomic environments as structure intrinsic obstacles for both dislocation motion and crack propagation. F

By a numerical relaxation scheme we have simulated the plastic deformation of a quasicrystal. Shear stress was applied to a quasiperiodic icosahedral atomic configuration of Lennard-Jones particles, and nucleation of dislocation dipoles was observed
