Abstract

Plastic deformation in crystalline materials is caused by the motion of a large number of dislocations in the atomic structure. Modeling the behavior of dislocations is complicated because of their long-range interactions. In this report, we develop expressions to describe the elastic fields of discrete dislocations in Fourier space. By expressing the shear stress for a doubly periodic dislocation distribution as a discrete Fourier Transform, we obtain numerical results that are consistent with direct summation of the analytical expressions.
