Magnetic Field Mapping for Complex Geometry Defect - 3D Transient Problem
A 3D visualisation of transient magnetic field mapping via finite element simulation for the characterisation of complex geometry defect is presented in this paper. In this work, we nalyse the Pulsed Eddy Current (PEC) testing application on detection and characterisation of complex geometry defect, i.e. angular slots, through the mapping of magnetic field distribution subject to the interaction between eddy current and defects in conductive samples. The investigation is implemented via time-stepping 3D Finite Element Analysis (FEA). Finite Element (FE) simulations conducted in transient mode were explored for the characterisation of angular slots. The results indicate the potential of complex geometry defect characterisation based on the visualisation and mapping of the magnetic field distribution. It is expected that the investigation will help in sensor (array) design and inverse models for complex geometry characterisation.
