| Abstract: | In this paper,the scattered-light method with a laser light source is used to determine the mode I stress intensity factors of the central crack sheets under axial tensile stress. The experimental and analytical results show that, the scattered-light method is simpler than the general photoelasticity method and it can be used to improve the precision of the experiment results. The scattered-light method also possesses more advantages when it were applied to solve the three-dimensional problems in the fracture mechanics. |
