Crack Propagation in Icosahedral Model Quasicrystals

Abstract

Propagation of mode-I cracks in a three-dimensional model quasicrystal is studied by molecular dynamics simulations. The samples are endowed with an atomically sharp crack and subsequently loaded by linear scaling of the displacement field. The response of the system is then monitored during the simulation. In particular, the crack surface morphology is… (More)
