Abstract

Abstract

In order to study the linking between metal magnetic memory signal of ferromagnetic materials and stress, based on wavelet analysis the metal magnetic memory signal was decomposed into two parties, i.e., the large-scale approach and the detail section. The correlation dimension of the detail section was calculated and the relation of the correlation dimension to stress was investigated. It is shown that with increasing stress the correlation dimension decreases.
