A simple model for the contact problem of a finite cracked plate in bending

Abstract In bending of a finite cracked plate, the stress intensity factor (SIF) at a cracked tip is usually negative. This means that the displacement at the vicinity of the crack tip is overlapped. However, this is not reasonable. In this paper a simple model is suggested. When the SIF is negative, some part of the crack will close. By using a collocation method the length of the closed part of the crack, and the SIF value of the other crack tip have been calculated. The results are useful for engineering practice.
