Abstract: Different root shape of shear web, result different stress distribution of web, especially for the weak parts may be caused blade damage due to the stress superposition. This article discusses the influence of different web root shape on the stress distribution of dangerous area. By calling the proportion coefficient of web root excision shape to C-type form factor F, the paper uses three ways to discuss the C-type form factor. By combine the result of finite element analysis and practice, the best shape of web root was finally determined.

Key words: C-type form factor, stress, finite element analysis
