Simulation of Stress-magnetization Effect on 18CrNi4A Steel by ANSYS

摘要

To analysis the Stress-magnetization Effect on 18CrNi4A steel sample under the geomagnetic field, the mode of the sample and the air around it was constructed with the help of ANSYS, famous software of FEA. The stress and magnetic flux leakage distribution of the mode were given. The influences of stress concentration under the geomagnetic field on magnetic memory signal were discussed. Lastly, through the contrast analysis between finite element result and experimental phenomena, the summing-up was given, providing the gist for the further study of magnetic memory testing theory and experiment.
