Abstract

3D physical modelling and Finite Element Analysis (FEA) have been performed to investigate individual sensor's performances fabricated from highly sensitive advanced state of the art semiconductor heterostructure materials which have been developed at the University of Manchester, and to explore Magnetic Flux Leakage (MFL) NDT configurations using a prototype 2D DC Magnetic Field Camera constructed from those sensors. The 3D physical simulation successfully predicted the sensitivities of the individual sensor, and the quantitative values match very closely to those obtained from experiments. The 3D FEA simulations successfully produced magnetic images which were validated qualitatively by the prototype 2D DC Magnetic Field Camera. As the simulations were performed prior to the experiments it can be inferred with confidence that the developed simulations can be used as an effective means of verifying experimental setups prior to their construction and hence are essential means of time and cost management in the ever pressing NDT arena.
