The method of images was used to derive the solution of a screw dislocation under time-harmonic conditions for an elastic strip from the solution of infinite planes. The displacement and stress components were obtained for a strip under concentrated antiplane time-harmonic traction. The dislocation solution was employed to formulate integral equation for a strip weakened by cracks and cavities. The effects of load frequency and crack orientation on the stress intensity factors were studied.
