| Abstract: | Stress field of internal loaded dural ring with two radial cracks are investigated by using photo-elasticity method. Isochromatic patterns near crack tips are obtained and their stress intensity factors calculated. A new approach is proposed in which loaded to inner radius of ring-shaped region by means of core-bar. |
