The Study of the Magnetic Memory's Magneto-Mechanical Coupled Effect Based on ANSYS

摘要

In the paper, a magneto-mechanical coupling model is established to study the magnetic memory's magneto-mechanical coupled effect, and then the finite element analysis software ANSYS is used to simulate the relationship between the parameter of three kinds of pipeline defects and their magnetic leakage field's normal component peak-peak value. The result proves the relationship between the stress concentration and the magnetic memory effect.
