Tangential Component Signals of Metal Magnetic Memory Testing

The method of resultant vector was adopted to extract tangential component signals of metal magnetic memory due to the problem that the tangential component signals of metal magnetic memory is very hard to be extracted,and the validity of this method is verified by ANSYS simulation.The relationship between tangential component signals of magnetic memory and stress concentration position as well as stress concentration degree has been studied by tensile testing,and the K curve of tangential component signals of magnetic memory has been analyzed.The results show that the tangential component signals of metal magnetic memory can be effectively extracted by the method of resultant vector;and the stress concentration position and stress concentration degree can be reflected intuitively and accurately by tangential component signals of metal magnetic memory.It is proved that the stress concentration position and stress concentration degree can be effectively determined by tangential component signals of metal magnetic memory.
