Crack-crack interactions in bimaterials
Engineering Fracture Mechanics, 1993Abstract The effect of a small crack on the SIF at the tip of a neighbouring main crack is studied using the finite element method. Both collinear and stacked parallel arrangements are examined. Two extreme orientations of cracks with respect to the interface are considered.

Cracks and Crack Control in Concrete Structures [PDF]
PCI Journal, 1988 T he material presented in this paper is based on more than 30 years of research, observations and experience concerning causes, control, and consequences of cracking in concrete structures. This extensive background was helpful in the preparation of this paper which deals with questions of concrete cracking.

Crack-crack and crack-pore interactions in stressed granite
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979Abstract Scanning electron microscope observations of stress-induced crack growth, causing crack-crack and crack-pore interactions within individual grains of Barre granite, show that photoelastic models of cracks are essentially correct and applicable to rock.

Analysis of crack-dislocation interaction: crack closure, crack opening
Materials Science and Engineering: A, 1994Abstract The decrease in stress intensity factor, expected from dislocation emission at a crack tip, can be achieved either through a change in crack tip radius (blunting) or through a crack closure induced by the dislocation (shielding) opposite to the opening imposed by the external stress field.

Fracture: To Crack or Not to Crack. That Is the Question
2015The expansion of the theory of fracture is one of the most exciting and thought provoking intellectual construct in continuum mechanics. In a period of almost a century, it required the combination of ingredients of differing nature: acute experimental observations, clever reasoning both in elasticity and thermodynamics, introduction of plasticity ...

Abstract Loaded slit cracks are modelled as continuous distributions of dislocations with infinitesimal Burgers vectors. Cauchy-type singular integral equations for the density of Burgers vector in these distributions are solved using the theory of Chebyshev polynomials.

Abstract The subject of this paper is the application of basic ideas and methods of continuum mechanics to the crack propagation processes. The crack extension is governed by an additional condition at the crack-tip. As a consequence of this a problem of “fine” structure of the crack-tip is considered.

The problem of a crack at the interface between dissimilar elastic media is of considerable contemporary importance in Elasticity, because of its relevance to the problem of debonding of composite materials and structures. Figure 24.1 shows the case where such a crack occurs at the plane interface between two elastic half-spaces.

The purpose of our design project is to produce a high purity hydrogen product that emits a low concentration of carbon dioxide emissions. The objective will be to replace the current industrial standard of steam reforming which doesn't produce a marketable byproduct as well as producing high amount of carbon dioxide emissions. Throughout the semester,
