Some practical crack path examples
Fracture and Structural Integrity, 2013 It is well known that many engineering structures and components, as well as consumer items, contain cracks or crack-like flaws. It is widely recognised that crack growth must be considered both in design and in the analysis of failures.

Crack paths and the linear elastic analysis of cracked bodies [PDF]
Fracture and Structural Integrity, 2015 The linear elastic analysis of cracked bodies is a Twentieth Century development, with the first papers appearing in 1907, but it was not until the introduction of the stress intensity factor concept in 1957 that widespread application to practical ...

Crack path predictions and experiments in plane structures considering anisotropic properties and material interfaces [PDF]
Fracture and Structural Integrity, 2015 In many engineering applications special requirements are directed to a material's fracture behavior and the prediction of crack paths. Especially if the material exhibits anisotropic elastic properties or fracture toughnesses, e.g.

Assessment of 3D Short Crack Closure in Ti-6Al-4V Alloy Utilizing Synchrotron X-ray Microtomography [PDF]
MATEC Web of Conferences, 2020 Synchrotron X-ray microtomography was utilized to observe the complex 3D crack morphology and the closure behavior of a short crack in Ti-6Al-4V alloy. The aim of the study was to investigate the effect of the crack path evolution on the 3D short crack ...

Crack path selection in orientationally ordered composites [PDF]
Physical Review E, 2020 While cracks in isotropic homogeneous materials propagate straight, perpendicularly to the tensile axis, cracks in natural and synthetic composites deflect from a straight path, often increasing the toughness of the material. Here we combine experiments and simulations to identify materials properties that predict whether cracks propagate straight or ...

Controlling fatigue crack paths for crack surface marking and growth investigations
Fracture and Structural Integrity, 2015 While it is well known that fatigue crack growth in metals that display confined slip, such as high strength aluminium alloys, develop crack paths that are responsive to the loading direction and the local microstructural orientation, it is less well ...

Influence of control parameters on the crack paths in the aluminum alloy 2024 under bending [PDF]
Fracture and Structural Integrity, 2015 The paper presents development of crack paths in aluminium alloy 2024. Fatigue tests were carried out for specimens with rectangular cross-section. The specimens were put to bending at controlled energy parameter amplitude and bending moment amplitude.
