Crack-crack interactions in bimaterials

Engineering Fracture Mechanics, 1993
Abstract 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.

INTERACTION EFFECTS OF MULTIPLE CRACKS

17th Structures, Structural Dynamics, and Materials Conference, 1976
As a result of the physical and thermal tests on compressed cone to flat metallic contacts it is possible to predict the thermal conductance of this type of joint with confidence. Parameters required for these predictions include the shape of the deformed joint whilst loaded, and the true support pressure. The latter varies with the initial cone angle,

Crack interaction in composites

35th Structures, Structural Dynamics, and Materials Conference, 1994
This work is concerned with the interaction of a macro-crack with a micro-crack in a cross-ply composite laminate. Two macro-cracks; matrix cracks and delaminations are considered, interacting with the matrix micro-cracks. The micro-cracks are both, normal and at an angle to the macro-cracks.

Crack-crack and crack-pore interactions in stressed granite

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979
Abstract 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.

Interaction of cracks with other cracks or boundaries

International Journal of Fracture Mechanics, 1972
Thin strips made of plexiglas and containing either two symmetric and collinear edge cracks or an edge crack close to a boundary were subjected to tension. If these strips were viewed in a coherent monochromatic light beam emitted from a He-Ne gas laser, the light reflected from the back surface of the strip deviated because of the highly strained zone

Analysis of crack-dislocation interaction: crack closure, crack opening

Materials Science and Engineering: A, 1994
Abstract 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.

On crack-crack interaction and coalescence in fatigue

Engineering Fracture Mechanics, 1982
Abstract The effect of crack-crack interaction and coalescence in fatigue was studied for a single pair of cracks analytically and for multi-cracks based on real microstructure variations by means of Monte Carlo simulations. Crack-crack interaction and coalescence lower the mean fatigue lifetime.
