The angular and radial dependencies of the mirror‐mist boundaries predicted by the stress‐intensity and Johnson‐and‐Holloway criteria were compared with experimentally determined shapes of the boundaries in rectangular specimens fractured in tension and flexure. The stress‐intensity criterion provided better predictions than the Johnson‐and‐Holloway criterion.
