Abstract

The method for determining the height of the surface microirregularities by means of a pseudostereopair, which can be used to determine the geometry of the start zone of the brittle separation crack, is completed and automated. The possibility of using the proposed method for investigating the stretch zone of compact specimens of the OSL steel is considered. The stretch zone of the railway axis steel is investigated using the proposed technique.
