Expressions were derived for the displacement and stress fields of a sinusoidal edge dislocation in an infinitely extended isotropic medium. It was suggested that information concerning the physical properties of non-planar cracks which propagated along <110> in intermetallics with cubic structures could be obtained by studying particular cracks which consisted of continuous distributions of sinusoidal edge dislocations that were perpendicular to (110) and had infinitesimal Burgers vectors.
