ACCURACY ANALYSIS ON THE EMPIRICAL EQUATION OF FINITE THICKNESS SEMI-ELLIPTICAL SURFACE CRACK BASED ON INTERACTION INTEGRAL METHOD

ACCURACY ANALYSIS ON THE EMPIRICAL EQUATION OF FINITE THICKNESS SEMI-ELLIPTICAL SURFACE CRACK BASED ON INTERACTION INTEGRAL METHOD

The interaction integral method（IIM） is used to calculate stress intensity factors（SIF） of finite thickness semi-elliptical surface cracks. Results are compared with that predicted by the empirical equation and equivalent domain integral（EDI） method. The comparison with EDI method verifies computati...
