Plane Elasticity and Dislocation of One-Dimensional Hexagonal Quasicrystals with Point Group 6.

摘要

Plane elasticity theory of one-dimensional hexagonal quasicrystals with point group 6 is proposed and established . As an application of this theory, one typical example of dislocation problem in the quasicrystals is investigated and its exact analytic solution is presented. The result obtained indicates that the stress components of elastic fields of a straight dislocation in the quasicrystals still first order singularity, which is the same as the general crystals, but are related with the Burgers vector of phason fields, which is different from the general crystals.
