| Abstract: | This paper deals with the theory of fracture anti - derivation technique. The at data from fracture suffoce in bolt hole are analysed by fatigre and damage tolerance and it is used to determine crack growth curve and crack growth cycle. A numerical example has been given in which excellent agreenent is found beween estimates and experimental results.A new idea is present in this paper. |
