Crack path stability in cracked panel
Journal of the Chinese Institute of Engineers, 2004Abstract The prediction of the crack growth path plays a significant role in the estimation of the final shape of broken solids and structures. Furthermore, the study of the crack path in broken specimens renders the loading conditions just before fracture.

Path stability of a crack with an eigenstrain
Journal of Mechanical Science and Technology, 2006A slightly curved crack with an eigenstrain is considered. Solutions for a slightly curved crack in a linear isotropic material under asymptotic loading as well as for a slightly curved crack in a linear isotropic material with a concentrated force are obtained from perturbation analyses, which are accurate to the first order of the parameter ...

In relation to fatigue crack growth, it is observed that long cracks under mixed mode loading conditions branch to follow the direction along which \(\Delta k_{\text{II}}\) is zero, but some results against this local symmetry criterion are also reported.

Simple probabilistic models of fracture of 3D polycrystals involving transgranular and intergranular cracks are based on undamaged paths and appropriate percolation thresholds. In a second part, theoretical extensions of phase field models for crack initiation and propagation to the case of locally heterogeneous and anisotropic fracture energy are ...

Computational crack path prediction
Theoretical and Applied Fracture Mechanics, 1985Abstract A computer program has been developed for the numerical prediction of curved crack growth paths under proportional loading conditions. The numerical prediction is performed by the step-by-step method in cooperation with the stress analysis ahead of the crack tip and the determination of the curved increment of the crack growth.

The reliability of a joint subjected to mechanical and thermal loads during processing and service constitutes a major technical problem. Joints contain flaws. The observed strength of a joint depends upon the location and size of the flaws, as well as the crack path through the joint.

Crack closure and crack path prediction for curved cracks under thermal load
Engineering Fracture Mechanics, 1993Abstract Based on an integral equation formulation, a boundary element method is presented for the analysis of curved cracks under mechanical and thermal load. It takes into account possible load and crack shape-dependent crack closure effects. In conjunction with a suitable crack growth criterion, the method enables, by means of an incremental ...

[Crack path in dental amalgams].
Odontostomatologike proodos, 1991The need of amalgam to resist fracture becomes a more evident necessity when restoration margins are taken into consideration. Marginal microcracks permit bacteria to pass beneath the restoration resulting in cement base dessalution, secondary caries and pulp inflammation.

Notes on the paths and stability of cracks
International Journal of Fracture Mechanics, 1966The stress distribution at the tip of a crack can be expanded as a power series. The first term, usually called the stress intensity factor, determines the initiation of fracture in a brittle material. In this paper it is shown that the second, third and fourth terms have the following effects: (a) the second term controls the stability of the ...
