Overload effects have been studied for center-cracked tension (CCT) specimens of aluminum alloy 2124-T351. The results show that the retardation of crack propagation due to overloading, which is not taken into account by the Paris relation, can be explained by variation in the U ratio as defined by Elber.

Advanced Materials Research, 2014
In this paper, an analytical method is presented for crack growth threshold criterion based on calculation of dynamic stress intensity factors (DSIF) in the mixed mode. The basis of the method is comparison of DSIF and fracture toughness. The analytical method is grounded on solving two-dimensional wave equations in the frequency domain, using complex ...

Fatigue & Fracture of Engineering Materials & Structures
ABSTRACTThree‐dimensional (3D) cracks emanating from various stress concentrations are frequently encountered in aircraft structures. The stress intensity factor (SIF) is a key element for damage tolerance analysis. In this paper, 3D SIFs are calculated by the slice synthesis weight function method (SSWFM) and used for fatigue crack growth (FCG ...
