Crack kinking at the tip of a mode I crack in an orthotropic solid [PDF]
International Journal of Fracture, 2017 The competition between crack penetration and crack kinking is addressed for a mode I macroscopic crack in an orthotropic elastic solid. Cohesive zones of finite peak strength and finite toughness are placed directly ahead of and orthogonal to the plane of the parent crack.

The crack kinking out of an interface [PDF]
Theoretical and Applied Mechanics, 2005 Kinking of a plane strain crack out of an interface between the two dissimilar isotropic elastic materials is analyzed. Analysis is focused on the initiation of kinking and thus the segment of the crack leaving the interface is imagined to be short ...

Enhancing the Resistance to Shear Instability in Cu/Zr Nanolaminates Through Amorphous Interfacial Layer [PDF]
NanomaterialsMetallic nanolaminates generally show ultra-high strength but low ductility due to their vulnerability to shear instability during deformation. Herein, we report the simultaneous enhancement in hardness (by 11.9%) and suppression of shear instability in ...

On a kinked crack model to describe the influence of material microstructure on fatigue crack growth [PDF]
Fracture and Structural Integrity, 2013 Threshold condition and rate of fatigue crack growth in both short and long crack regime appear to be significantly affected by the degree of crack deflection.

Fracture morphology and its evolution A review on crack path stability and brittle fracture along butt-weld [PDF]
Fracture and Structural Integrity, 2015 Considerations are made for the fracture morphology and its evolution in relation to the brittle fracture along butt-weld, where crack path stability may play important roles in various aspects. Analyses of a kinked and curved crack are first reviewed in

Variable mode-mixity during fatigue cycles – crack tip parameters determined from displacement fields measured by digital image correlation [PDF]
Fracture and Structural Integrity, 2017 This paper focusses on discussing equivalent stress intensity factors and kink angles after a change of mode-mixity from one cycle to the next and when the mode-mixity changes continuously during the fatigue cycles.

Investigation of mixed mode fatigue crack propagation in SEN-specimen under in-phase and out-of-phase conditions due to tension-compression and torsional loading [PDF]
MATEC Web of Conferences, 2019 Numerous cases of damage by fatigue in structures are related to mechanical stresses due to mixed mode loading conditions. To prevent such cases of failure a precise knowledge of the corresponding theoretical background is indispensable.
