Quantification for length and depth of crack is important content in the pulsed eddy current(PEC) non-destructive examination(NDE).A novel PEC probe based on magnetic-concentrating technique is proposed.Simulation models of typical PEC probe and novel PEC probe are established by ANSYS software
and the length-quantification results from the two probes are compared and analyzed.The simulation results reveal that novel PEC probe could realize accurate quantification on the crack length and depth parameter.The simulations’ correctness is experimentally testified by experiment results
and it shows that the novel PEC probe is valid.
