FIELD: metallurgy.
SUBSTANCE: plastic deformation is created on edges of a specimen. The following is used for creation of plastic deformations: local heating, rolling and combination of those methods of action; as a result, in the centre of the specimen a zone with uniform distribution of stress components appears, the signs and levels of which depend on the nature of action and can be found as per the measurement results of the specimen before and after the action.
EFFECT: improving accuracy of measurement results of mechanical stresses in steel structures.
