Anti-shielding of a crack tip by a dislocation is examined at the atomistic level for a simple geometry to test classical singular-crack and recent cohesive-crack models of crack/dislocation interactions. The atomistic model shows that, as an anti-shielding dislocation approaches the crack tip, it c

Crack tip shielding by dislocations is an essential feature of the modeling of semi-brittle crack propagation and the brittle to ductile transition. The stress field, in the elementary configuration where a single dislocation interacts with a crack, is obtained by two independent methods, at two dif
A mathematical formulation is developed for a long crack (mode III) with two symmetrical screw dislocation pileups inclined to the crack by an angle 4. Dislocation free zones (DFZ) are allowed at the crack up. The resulting series of equations are solved numerically. The effect of the inclination an
hvo dimensional distribution of dislocations compatible with slip line theory is used to simulate the plastic flow near the mode II crack tip. On the basis of this model, the critical shear stress 7c is derived from the variational form of the energy principle. In comparison with the critical tensil
The distribution of dislocations in the vicinity of a mode I crack tip is formulated based on the observation of a single crystal specimen of aluminium by transmission electron microscopy (TEM). Closed form expressions of the dislocation density function and the dislocation-free zone (DFZ) condition
