| Abstract | The role of residual stresses in the failure of metallic components and the need to determine such stresses is well recognised. Magneto-acoustic emission (MAE) is a relatively new non-destructive detection technique and its working principle is based on Barkhausen discontinuities or noise and magnetostriction when a ferromagnetic material is subjected to a varying magnetic field. MAE is being used to characterise the stress state of a ferritic stainless steel (AISI 430). Other stress measurement techniques; X-ray diffraction (XRD), magnetic Barkhausen noise (MBN) have also been used to confirm / support the results achieved using MAE. A new measurement parameter has been developed for stress characterisation called MAE absolute energy and has proved to be a useful quantitative method in MAE waveform measurement. I can’t seem to get to grips with this last sentence. When you say stress characterisation, what do you mean? |
