A defect in a crystal lattice where a row of atoms is missing is called an edge dislocation. The stress field around an edge dislocation is given by:

where G is the shear modulus, b is the Burgers vector, and v is Poisson's ratio. Plot the stress components (each in a separate figure) due to an edge dislocation in aluminum, for which G = 27.7 × 109 Pa, b = 0.286 × 10-9 m, and v = 0.334. Plot the stresses in the domain. -5 × 10-9
