Сравнение двух способов обработки экспериментальных данных в магнитном методе для определения упругих сжимающих напряжений

Abstract

The field dependences of the measurement coil signals, U~(H), on the sample of St3 mild steel have been experimentally obtained under elastic compression. For each load, corresponding to the irreversible translations of 900 domain walls maximum fields were de-termined by two techniques. The magnetoelastic fields Hσ and mechanical stresses σicalc were calculated. The results obtained by two different techniques were found to be in a good ag-reement.
