Abstract：By using the famous complex variable function method introduced by Muskhelishvili and the analytic function theory in this paper, the analytical solutions of the interaction of many parallel screw dislocations with a finite crack in infinitely large one-dimensional hexagonal quasicrystals are studied. The field intensity factors at the crack tip and the imaged force acting on one dislocation with the existence of crack and other dislocations are obtained. The numerical examples are given to discuss the influence of the dislocation position on the field intensity factors and the imaged force. And the position and distribution of the dislocations also effect the generalized stress field.
