Crack interaction modelling

Fatigue & Fracture of Engineering Materials & Structures, 2000
The growth characteristics of short fatigue cracks under axial loading were investigated using specimens of the ferritic–martensitic steel F82H‐mod. Interest focused on crack propagation due to coalescence, which proved to be the dominant mechanism of crack growth.

Dislocation-crack interaction

Journal of Physics and Chemistry of Solids, 1987
Abstract In this paper, recent developments in the understanding of the dislocation-crack interaction and its relationship to the phenomena of crack tip deformation and fracture toughness are reviewed. An enhanced research activity in this area began with successful observations of the behavior of crack tip dislocations by various techniques, namely ...

Interaction of a dislocation with a crack

Journal of Applied Physics, 1983
A solution is given of the field equations of nonlocal elasticity for a line crack interacting with a screw dislocation in an elastic plane under antiplane shear loading. Displacement and stress fields are determined throughout the core region and beyond.

Interaction of a penny-shaped crack with an elliptic crack

International Journal of Fracture, 1995
Three-dimensional problem of crack-microcrack interaction is solved. Both the crack and microcrack are embedded in an infinite isotropic elastic medium which is subjected to constant normal tension at infinity. One of the cracks is circular while the other is elliptic and they are coplanar and are positioned in such a way that the axis of the elliptic ...

A PIEZOELECTRIC INHOMOGENEITY INTERACTING WITH A BRANCHED CRACK

International Journal of Computational Methods, 2006
This paper deals with the interaction between a circular piezoelectric inhomogeneity (a circular piezoelectric fiber sensor) and a symmetrically branched crack. The piezoelectric inhomogeneity is embedded in a nonpiezoelectric, elastic matrix with a symmetrically branched crack near the inhomogeneity.

Interaction of Shear Waves and Propagating Cracks

Physical Review Letters, 2003
Shear waves generated from an ultrasonic transducer are used to twist dynamically growing crack fronts; the response of crack front to such external perturbations is examined in order to investigate the primary cause of surface roughening in brittle materials.

Interaction of Sound with Fast Crack Propagation

Physical Review Letters, 1998
The influence of ultrasounds on crack dynamics in brittle materials is experimentally studied by using both the natural sound emitted by the propagating crack and an artificially generated ultrasound burst. We show that, although the acoustic energy is only 5% of the energy needed to propagate the crack, the presence of sound waves in the specimen ...

Interaction between crack deflection and crack bridging

Journal of the European Ceramic Society, 1992
The potential of crack deflection and crack bridging as competing toughening mechanisms is reviewed. Available measurement techniques take a crucial role where it is required to distinguish between toughening increments associated with crack tip processes and crack wake processes near the crack tip.
