Va. Lubarda et Da. Kouris, STRESS-FIELDS DUE TO DISLOCATION WALLS IN INFINITE AND SEMIINFINITE BODIES, Mechanics of materials, 23(3), 1996, pp. 169-189
Stress fields due to dislocation walls in infinite and semi-infinite b
odies are derived. Finite, infinite, and semi-infinite walls of identi
cal edge dislocations with uniform spacing are considered. The results
corresponding to walls with discrete dislocation distributions are co
mpared to those of the walls with continuous distribution of infinites
imal dislocations. The stress relaxation effects produced by the free
surface in the neighborhood of a dislocation wall are studied. It is s
hown that the long range stresses are exerted by bounded walls in both
infinite and semi-infinite bodies. The stress divergence or its absen
ce is discussed for various wall configurations.
