| Abstract: | A wide steel plate sample has been used to invesdgate the effect of stress on theBarkhausen noise, The relation between the rotational excitation field magnetization and theorientation of magnetization extreme value for anisotropic materials has been found and anew way of measuring the stress in iron and steel parts investigated. The improvement of ac-curacy in measuring the stress by a combination of the BN and MAE approaches is suggest-ed. |
