The effect of a lattice friction stress on the monotonic growth of a plane strain mode I crack under small-scale yielding conditions is analyzed using discrete dislocation plasticity. When the friction stress is increased from zero to half the dislocation nucleation stress, the crack tip stress field changes from one characteristic of a plastic solid to one characteristic of an elastic solid, and the crack growth resistance decreases substantially.
