Abstract
The relationship between shear cracks and double-ended dislocation arrays is discussed. The density of a double-ended dislocation array under the uniform applied shear stress was calculated by the shear-crack conversion method. The calculated density agrees with that calculated from the dislocation model. A general method of calculating the dislocation densities near the spearheads of dislocation arrays is given. Examples are illustrated; in general, the density as well as the stress and strain fields near the spearhead of a single-ended linear dislocation array are higher than those of a double-ended array under the same applied stress on the slip plane.This publication has 8 references indexed in Scilit:
