[Crack path in dental amalgams].

Odontostomatologike proodos, 1991
The 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.

Thermoelastic Investigation of Crack Paths

2007
Traditionally fracture mechanics is mostly concerned with the opening mode of crack growth. Stability and crack path problems are relatively well understood in this case and it is expected that a crack grows in its own plane. However, cracks may exist in different orientations and moreover more than one crack may be found in a structure.

Crack Paths in Brittle Solids

2014
We analyze a kinked and curved crack in an elastic body by using the first order perturbation method, where the result is applied to a straight crack with a slightly kinked and curved crack extension in a finite body. Crack path criteria are discussed for the crack path prediction in brittle solids, which may also lead to some considerations about the ...

Crack-Path Effect on Material Toughness

Journal of Applied Mechanics, 1990
The material-toughening mechanism based on the crack-path deflection is studied. This investigation is based on a model which consists of a macrocrack (semi-infinite crack), with a curvilinear segment at the crack tip, situated in a brittle solid. The effect of material toughening is evaluated by comparison of the remote stress field parameters, such ...

The linear elastic analysis of cracked bodies and crack paths

Theoretical and Applied Fracture Mechanics, 2015
Abstract 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 engineering problems became possible.

Hydrogen-induced cracking in iron: Morphology and crack path dependence

Metallurgical Transactions, 1970
Cathodic charging of purified iron with hydrogen at room temperature and in the absence of an external stress results in the formation of intergranular and/or transgranular cracks for all purities of iron examined. The transgranular cracks are crystallographic, forming on variants of {110} or possibly {112} planes.

Five decades of crack path research

Engineering Fracture Mechanics, 2010
The complete solution of a crack propagation problem includes determination of the crack path. At the present state of the art the factors controlling the path taken by a propagating crack are not completely understood. In the last five decades there have been substantial advances in the understanding and prediction of both macroscopic and microscopic ...
