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.

Fatigue crack propagation analysis considering the dynamic crack-load coupling effect [PDF]
Scientific ReportsGear fillet crack is one of the most common defects of the gear transmission system, and the study of gear fillet crack propagation and life prediction has attracted much attention in the literature. The existence of the crack will alter the dynamic load

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

Propagation behavior of two collinear mode Ⅰ cracks driven by explosive gas
矿业科学学报, 2023 In smooth pre-splitting blasting, two collinear cracks extending opposite to each other between adjacent holes will first avoid each other and then attract each other, resulting in crack propagation path that often presents hooked or butterfly-shaped ...

3D modelling of fatigue crack growth and life predictions using ANSYS
Ain Shams Engineering Journal, 2022 This study uses ANSYS mechanical APDL 19.2 to predict crack propagation trajectories and fatigue crack growth at constant amplitude loading. Mixed-mode fatigue life assessment is implemented by the Paris law model for different configuration of modified ...

Equivalent Stress Intensity Factor: The Consequences of the Lack of a Unique Definition
Applied Sciences, 2023 The concept of an equivalent stress intensity factor Keq is used in the study of fatigue crack growth in mixed-mode situations. A problem seldom discussed in the research literature are the consequences of the coexistence of several alternative ...

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 ...

Non steady-state intersonic cracks in elastomer membranes under large static strain [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2021 Dynamic crack propagation in elastomer membranes is investigated; the focus is laid on cracks reaching the speed of shear waves in the material. The specific experimental setup developed to measure crack speed is presented in details.
