Characterisation of surface and sub-surface discontinuities in metals using pulsed eddy current sensors [PDF]
Due primarily to today's rigorous safety standards the focus of non-destructive testing (NDT) has shifted from flaw detection to quantitative NIDT, where characterisation of flaws is the objective.
