Investigation of Influence on Mechanical Stress to Change in Magneto Noise and Magneto Electro-acoustic Characteristics in Ferromagnetic Steel

The paper presents the results of complex research on low carbon steel S235. The research was carried out using electromagnetic methods, the Barkhausen noise method and a magnetic-acoustic emission method with the Multitest-MS10 equipment developed at the Institute of Mechanics (IMech) – Bulgarian Academy of Sciences (BAS)
