Mechanism of crack branching in the fatigue crack growth path of 2324-T39 Aluminium alloy [PDF]
Fracture and Structural Integrity, 2016 The crack growth behavior in 2324-T39 aluminium alloy was experimentally investigated. Two types of crack branching were observed. The mechanism of an uncommon crack branching which results from the link up of secondary crack with the main crack was ...

Interaction of Multiple Cracks on Crack Propagation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000 There is interaction among multiple cracks which are initiated in a plane surface by fatigue or environmentally assisted cracking. And it is observed that these cracks may coalesce as they approach each other. In this study, the interaction of multiple cracks with different relative locations and lengths was evaluated using a finite element method ...

Unloading-Induced Crack Propagation of Two Collinear Unequal Length Flaws in Brittle Rocks
Geofluids, 2020 The propagation and coalescence of numerous discontinuous joints significantly contribute to landslide instability during excavation unloading. The tip expression of stress intensity factors of two collinear unequal length cracks in a typical rock mass ...
