| Abstract: | This paper gives the complex stress function of preformed V shape fracture under the blasting load. With Westergaard's method, the stress field and displacement field of preformed V shape fracture tip are derived, and hence its stress intensity factor is obtained. The blasting test result shows that the formulas derived are correct and effective |

| Keywords: | V shape fracture complex stress function stress intensity factor |
