Shrink fit is widely used in joining mechanical components and combining prestressed cylinder to increase their elastic strength. However, many serious accidents have occurred because of the fatigue or fracture due to contact pressure between components. In this paper, stress intensity factors were obtained by simulating boss shaped parts with cracks,i.e., inserting a disk into a hollow disk, thus causing contact pressure in the inner surface of the hollow disk. Photoelastic methods were employed to determine the stress intensity factors which could describe the dynamic behavior in the vicinity of crack tips. The effects of shrinkage allowance and crack depth on the stress intensity factorys were examined.
