Abstract
An investigation of stresses around the edge of a 50% through-wall 'ra ce-track' (elongated pit) defect introduced into a steel beam sample w as conducted. Stresses were measured by Magnetic Barkhausen Noise (MBN ) using a magnetic disk read-head as the detector for the MBN probe. T he study also examined the change in Magnetic Flux Leakage (MFL) signa l as a function of increasing applied bending stress. Experimental res ults were compared to numerical calculations obtained from a finite el ement stress modelling package and found to be in good agreement.
