TO THE QUESTION OF THE STANDARD OF MECHANICAL STRESSES
(pp. 28-37)

Abstract. The results of a study of a biaxial stress-strain state using neutron diffraction, standardized in the field of stress measurement, and the Barkhausen effect method are presented. The possibility of using a device with a biaxial load as a standard of stress is evaluated. The article gives an assessment of an error in measuring voltage using strain gauges in relation to measurements made by the neutron diffraction method. The Barkhausen effect method is used as one of the non-destructive testing methods that are sensitive to the stress-strain state. The studies describe the possibility of adapting this method to the proposed stress standard.

Keywords: neutron diffraction, Barkhausen effect, deformation, strain gauge, biaxial loading, stress tensor, stress diffractometer, magnetic noise analyzer, voltage standard.
