Crack propagation in quasicrystals
R. Mikulla, J. Stadler, F. Krul +2
Crack propagation is studied in a two dimensional decagonal model quasicrystal. The simulations reveal the dominating role of highly coordinated atomic environments as structure in…

Dislocations in quasicrystals and their interaction with cluster-like obstacles
R. Mikulla, P. Gumbsch, H. -R. Trebin
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…
