The elastic field induced by a straight dislocation in a one‐dimensional hexagonal quasicrystal with its line parallel to the quasiperiodic axis is obtained by superposition of the elastic fields of a pure edge part and a pure screw part. By extending the Peach‐Koehler force to quasicrystals, the force between two parallel screw dislocations is given. For a screw dislocation in this quasicrystal of general cross‐section, the elastic field and the image force on the dislocation are given via the conformal mapping method.
