Stress Field of an Edge Dislocation

Here is a well known representation of the stress field surrounding an edge dislocation
On the left half of the picture, the stresses on the elementary cube are shown around the dislocation. Since there is no stress perpendicular to the image plane, a two-dimensional representation is sufficient.
On the right half, contours of equal stress are shown for the normal component and the shear components of the stress tensor.
