Diagnostically Oriented Magnetomechanical Effects Analysis in Quasi Static Low Magnetic Field
Przemysław Szulim , Szymon Gontarz
AbstractThe aim of the work is to try to separate two informations related to the magnetization of the material and the change in its magnetic permeability during the tensile test. These two parameters, in accordance with the adopted model, are associated with reversible and irreversible magnetomechanical effects present in the material degradation process. For extracting the material features, stimulation was performed using a slow-changing magnetic field with a value close to the natural field of the earth. For the observation field on the sample surface an original matrix of triaxial magnetic field sensors was used. Several measuring series were made for various construction steels for various load stages, both for the area of elastic and plastic deformation. The proposed approach together with the results from the conducted research allowed for a better identification of the magnetomechanical effects that carry diagnostic information about the material.
