FIELD: physics.
SUBSTANCE: article is magnetised with successive formation of two pronounced magnetic poles on the axis of symmetry of the cross-section profile on the entire length of the analysed article in order to form a symmetrical magnetic field relative the axis of symmetry of the cross-section profile of the article. The magnetic field induction value is measured at points on boundaries of the cross-section of the article, symmetrical to each other relative the axis of symmetry of the cross-section of the article along the length of the article. The point, direction and estimate of the bending stress in the article are determined from the difference in magnetic induction values at said symmetrical points.
EFFECT: ensuring a rapid process of detecting and estimating bending stress in structural material using stationary or mobile equipment.
