Brittle Fracture Assessment for Universal Coupling of 1300mm Blooming Mill

Chen Dahong (East China Institue of Metallurgy)Wang Fuyuan Zhao Zhouli (Baoshan Iron & Steel(Group)Corporation)  
With the investigation on the semielliptical crack and corner crack existing in the flat roll end of the main driving system of 1300ram blooming mill,and based on the deterministic fracture mechanics and probabilistic fracture mechanics,the deterministic assessment model and the reliability interference as- sessment model for the critical crack size of brittle fracture have been established, and some related examples are enumerated as well.
