Representative simulation results from discrete dislocation dynamics. The representative stress-strain behavior of the 45 simulations is shown in (a), while the representative total dislocation density evolution is shown in (b). Both are plotted with respect to the total strain, while the plastic strain values where dislocation configurations were extracted are shown. Both show the mean behavior at each timestep of the 45 simulations in black, while the shaded region represents one standard deviation away from the mean. a shows little strain hardening in the simulated regime. b shows a linear increase in the total dislocation density, roughly doubling across the regions of plastic strain we consider
