If determining the size and orientation of cracks, safe life of structural members can be evaluated. Mainly aircraft industries use Tone Burst Eddy Current Thermography (TBET) technique was used for the evaluation of crack damage in Aluminium plate or pipe like structures. This paper mainly describes about how the crack parameters mainly orientation affects distribution of temp produced by TBET heating. Parameter considered in this study is effect of crack orientation. 3D simulation results have been achieved by using COMSOL multi-physics with AC/DC module and general heat transfer. In TBET Technique at crack edges, induced current is seen concentrated thus indicating a localized high heating in those areas relative to other regions. It was determined that this technique has some advantages for the inspection aircraft structural components compared to other modalities, particularly in cracked regions.
