Abstract

Quasicrystal are intrinsically quasi-periodic crystalline structures in which local rearrangements of atoms (the so-called phason activity) occur during deformations and have a significant influence on the gross mechanical behaviour. By means of the wavelet analysis of some data obtained by numerical simulations, we show the interplay between standard deformations and atomic activity. In particular a four points bending test of a fissured beam is studied; the localizations around the crack are observed, both in static and dynamic settings.
