摘要：
Stress fields for wedge twins with various shapes of boundaries are calculated on the basis of a macroscopic dislocation model. It is shown that the deviation of a wedge twin from a symmetric shape leads also to the loss of symmetry in the stress-field distribution near the twin. Cases of a uniform and an equilibrium distribution of twinning dislocations at twin boundaries are considered.
