The formation of a plastic zone, in the form of a linear array of inclined edge dislocations in front of a mode I crack in plane strain, is studied. The direction of the force field on an edge dislocation due to the crack load allows for the determination of the plastic zone as a function of the inclination angl&. The dislocation distribution along the plastic zone is found from force equihibdum considerations. The results show the presence of a dislocation frce zone (DFZ) and a shrinking ofdoi:10.21236/ada175610 fatcat:ewgjhz52rzbmbbptmth47dbahu
