摘要：

The Stroh formalism for two-dimensional deformations of the icosahedral quasicrystal is studied, for which there are six pairs of complex eigenvalues. The closed-form expressions for the elastic displacement and stress fields induced by a dislocation in an icosahedral quasicrystal are obtained using the extended Stroh formalism. The effect of phonon-phason coupling elastic constant on mechanical behavior are also discussed. (C) 2012 Elsevier B.V. All rights reserved.
