Numerical Simulation of Infrared Nondestructive Testing to Metal Sample with Subsurface Defects

Abstract:

Article Preview

The transient heat transfer equation of the sample with defects is built. Numerical simulation of PT(Pulsed Thermography, ‘PT’) testing is done against C30Steel sample with hole defects via finite element method. Results show that, both the maximum value of the surface temperature and the time of the appearance of the inflection points change with the change of the defect diameter and depth. The surface temperature curves can be used for quantitative study of the defect characteristics.
