Abstract
The distribution of surface crazes in the vicinity of a stationary edge crack in a polystyrene sheet in tension is compared with the stress fields already investigated experimentally by Post. It is shown that the extent of crazing corresponds closely with the maximum principal stress contours determined experimentally and that the shapes of the crazes indicate that they grow along directions parallel to the minor principal stress axis.
