From: Multiscale modeling of dislocations: combining peridynamics with gradient elasticity
Stress field components of a singular dislocation in peridynamics, the Burgers vector points in x-direction and the glide plane trace corresponds to the x-axis; left: \(\sigma _{xy}(x,y=0)\), right: \(\sigma _{xx}(x=0,y)\); the top graphs show the original results for different values of the horizon where \(\delta _{\text {p}} =\) 3nm, 6nm, 9nm and 12nm (marked H3, 6, 9, 12 in the graph labels); the bottom graphs show the same data after rescaling \(\varvec{\sigma } \rightarrow \delta _{\text {p}} \varvec{\sigma }, \varvec{r} \rightarrow \varvec{r}/\delta _{\text {p}}\); in these graphs the locations of the collocation points at which virial stresses are evaluated are marked by open circles
