Abstract
Analytical calculations of the stress intensity factor offer a big time benefit compared to finite element simulations. In the present work, new approximate solutions for the stress intensity factor under tension and bending around two axes are proposed. Compared to already available solutions (e.g., by Newman and Raju), the proposed formulas extend the range of validity and comprise cases where the crack width 2·c and the crack depth a are close to the specimen width 2·B and the specimen thickness W, respectively.
