Modeling of edge cracks interaction [PDF]
Fracture and Structural Integrity, 2016 From experimental and theoretical investigations it is known that cracks are sensitive to geometry, e.g., to the inclination angle to the load. A small deviation of a crack from the normal direction to a tensile load causes mixed mode conditions near the

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 ...

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 ...
