Stresses of hexagonal screw dislocation arrays. III. Isolated dislocation cells incorporating hexagonal screw dislocation networks

Models of dislocation cells are constructed from aggregates of the hexapolar units studied in parts I and II, and their stresses are investigated by computer techniques. Two new features were investigated in particular. 1. The units' rotational stress fields combine to form long‐range rotational stresses about aggregates of the units which obliterate the hexapolar symmetry of the long‐range stresses that would otherwise have been expected. 2. …
