Simulation Analysis and Experimental Study of Initial Permeability Testing Technology

Abstract:

With the initial permeability testing technique, early evaluation on stress concentration and fatigue damage can be realized by measuring initial permeability of the ferromagnetic material. The variation of detection signals with initial permeability is researched via the ANSYS FEM simulation and the tensile testing of 45 steel. The results indicate that the detection signals have a linear relation with initial permeability of the ferromagnetic material. It is seen that initial permeability testing technology can give effective and accurate evaluation of the ferromagnetic material.
