DETERMINE THE DIRECTION OF THE STRESS IN THE ELASTIC ZONE OF DEFORMATION OF STEEL STRUCTURES USING A MAGNETIC CONTROL
The paper presents the method of determining the direction of the effective stresses using the magnetic method of nondestructive control of metal structures. The method takes into account the influence of the angle of magnetization relative to the line of loading on the value of the coercive force and to determine the direction of the stresses in the elastic zone of deformation of steel structures. Described the experiment with the bending of the I-beam profile № 10. Transverse bending of the beam allowed us to obtain zones of tension and compression in the metal with the same indicators of stress. Load selection was made based ensure only elastic deformation, so that the voltage does not exceed the yield strength. Shown and described according to the changes of the coercive force of the testing object from the angle between the line voltages and the axis side of the magnetic device for two different deformation zones.
