Modelling crack tip plastic zones and brittle-ductile transitions
Plasticity at crack tips has been modelled as self-organising arrays of dislocations emitted from a source near the crack tip. The model takes into account dislocation shielding, but not blunting. For materials where dislocation motion is slow, and the friction stress is high, the modelled arrays ar...
